Navios Maritime Midstream Partners GP LLC (the “General Partner”), a Marshall Islands limited liability company and wholly-owned subsidiary of Navios Maritime Acquisition Corporation (“Navios Acquisition”), was also formed on that date to act as the General Partner of Navios Midstream and receive a 2.0% general partner interest. In connection with the initial public offering (“IPO”) of Navios Midstream in November 2014, Navios Midstream acquired all of the outstanding shares of capital stock of four of Navios Acquisition's vessel-owning subsidiaries (Shinyo Ocean Limited, Shinyo Kannika Limited, Shinyo Kieran Limited and Shinyo Saowalak Limited) in exchange for: (i) all of the estimated net proceeds from the IPO amounting to $110,403; (ii) $104,451 of the $126,000 borrowings under Navios Midstream's new credit facility; (iii) 9,342,692 subordinated units and 1,242,692 common units; and (iv) 381,334 general partner units, representing a 2.0% general partner interest in Navios Midstream, and all of the incentive distribution rights in Navios Midstream, to our General Partner.

Segment Reporting [Abstract]
SEGMENT INFORMATION	NOTE 10: SEGMENT INFORMATION The Company reports financial information and evaluates its operations by charter revenues. The Company does not use discrete financial information to evaluate operating results for each type of charter. As a result, management reviews operating results solely by revenue per day and operating results of the fleet and thus the Company has determined that it operates under one reportable segment. Company monitors operating revenue by geographic region for the Company's reportable segment. Revenue is allocated on the basis of the geographic region in which the customer is located. Revenues from specific geographic regions which contribute over 10% of total revenue are disclosed separately. For the three and six month periods ended June 30, 2016 and 2015, all the revenues were derived from customers located in Asia. Vessels operate on a worldwide basis and are not restricted to specific locations. Accordingly, it is not possible to allocate the assets of these operations to specific countries.

Cash Distributions And Earnings Per Unit [Abstract]
CASH DISTRIBUTIONS AND EARNINGS/ (LOSSES) PER UNIT	NOTE 12: CASH DISTRIBUTIONS AND EARNINGS/ (LOSSES) PER UNIT The partnership agreement of Navios Midstream requires that all available cash is distributed quarterly, after deducting expenses, including estimated maintenance and replacement capital expenditures and reserves. Distributions may be restricted by, among other things, the provisions of existing and future indebtedness, applicable partnership and limited liability company laws and other laws and regulations. The amount of the minimum quarterly distribution is $0.4125 per unit or $1.65 per unit per year and is made in the following manner: • First, 98% to the holders of common units and 2% to the General Partner until each common unit has received a minimum quarterly distribution of $0.4125 plus any arrearages from previous quarters; • Second, 98% to the holders of subordinated units and 2% to the General Partner until each subordinated unit has received a minimum quarterly distribution of $0.4125; and • Third, 98% to all unitholders, pro rata, and 2% to General Partner, until each unit has received an aggregate amount of $0.4744. Thereafter there are incentive distribution rights held by the General Partner, which are analyzed as follows: Marginal Percentage Interest in Distributions Total Quarterly Distribution Total Amount Common and subordinated Unitholders General Partner Holders of IDRs Minimum Quarterly Distribution $ 0.4125 98.0% 2.0% 0% First Target Distribution up to $ 0.4744 98.0% 2.0% 0% Second Target Distribution above $ 0.4744 85.0% 2.0% 13.0% up to $ 0.5156 Third Target Distribution above $ 0.5156 75.0% 2.0% 23.0% up to $ 0.6188 Thereafter above $ 0.6188 50.0% 2.0% 48.0% On January 22, 2016, the Board of Directors authorized its quarterly cash distribution for the three month period ended December 31, 2015 of $0.4225 per unit. The distribution was paid on February 12, 2016 to all holders of record of common, subordinated, subordinated Series A units and general partner units on February 9, 2016. The aggregate amount of the declared distribution was $8,742. On April 21, 2016, the Board of Directors of Navios Midstream authorized its quarterly cash distribution for the three month period ended March 31, 2016 of $0.4225 per unit. The distribution was paid on May 12, 2016 to all holders of record of common, subordinated, subordinated Series A units and general partner units on May 6, 2016. The aggregate amount of the declared distribution was $8,742. For the period subsequent to the IPO, Navios Midstream calculates earnings per unit by allocating reported net income for each period to each class of units based on the distribution waterfall for available cash specified in Navios Midstream's partnership agreement, net of the unallocated earnings. Basic earnings per unit are determined by dividing net income by the weighted average number of units outstanding during the period. Basic and diluted net earnings per unit are the same because the Company does not have any potentially dilutive units outstanding for the period presented. In determining earnings per unit, the net loss for the period prior to the IPO, has been allocated to the general partner. Net loss per unit undistributed is determined by taking the distributions in excess of net income and allocating between common units, subordinated units and general partner units on a 98%-2% basis. The calculations of the basic and diluted earnings per unit are presented below.

Income Taxes

Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE 13: INCOME TAXES Marshall Islands, British Virgin Islands, and Hong Kong, do not impose a tax on international shipping income. Under the laws of Marshall Islands, British Virgin Islands, and Hong Kong, of the companies' incorporation and vessels' registration, the companies are subject to registration and tonnage taxes which have been included in the daily management fee. In accordance with the currently applicable Greek law, foreign flagged vessels that are managed by Greek or foreign ship management companies having established an office in Greece are subject to duties towards the Greek state which are calculated on the basis of the relevant vessels' tonnage. The payment of said duties exhausts the tax liability of the foreign ship owning company and the relevant manager against any tax, duty, charge or contribution payable on income from the exploitation of the foreign flagged vessel. Pursuant to Section 883 of the Internal Revenue Code of the United States (the “Code”), U.S. source income from the international operation of ships is generally exempt from U.S. income tax if the company operating the ships meets certain incorporation and ownership requirements. Among other things, in order to qualify for this exemption, the company operating the ships must be incorporated in a country, which grants an equivalent exemption from income taxes to U.S. corporations. All of the Company's vessel- owning subsidiaries satisfy these initial criteria. In addition, these companies must meet an ownership test. The management of the Company believes that this ownership test was satisfied prior to the IPO by virtue of a special rule applicable to situations where the ship operating companies are beneficially owned by a publicly traded company. For the period after the IPO, the Company believes that the second criterion can also be satisfied based on the trading volume and ownership of the Company's units but no assurance can be given that this will remain so in the future.
