          Re:      NUVEEN FLAGSHIP MULTISTATE TRUST IV
                   REGISTRATION STATEMENT ON FORM N-14
                   NUVEEN FLAGSHIP KENTUCKY MUNICIPAL BOND FUND


Ladies and Gentlemen:

          We are acting as counsel for Nuveen Flagship Multistate Trust IV, a
Massachusetts business trust (the "Trust"), in connection with the Trust's
filing of a registration statement on Form N-14 (the "Registration Statement")
with the Securities and Exchange Commission covering the registration of shares
of beneficial interest, $.01 par value per share, (the "Shares") of the Trust
designated Nuveen Flagship Kentucky Municipal Bond Fund (the "Acquiring Fund"),
pursuant to the proposed reorganization of its series of shares designated
Nuveen Flagship Kentucky Limited Term Municipal Bond Fund (the "Acquired Fund"),
as described in the Registration Statement and pursuant to that certain
Agreement and Plan of Reorganization dated December 18, 1998 by the Trust on
behalf of the Acquiring Fund and the Acquired Fund (the "Agreement").

          In that capacity, we have examined such business trust records,
certificates and other documents, and have made such other factual and legal
investigations as we have deemed necessary and appropriate for the purposes of
this opinion. In such examination, we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals, the
conformity to originals of all documents submitted to us as certified copies or
photocopies and the authenticity of the originals of such latter documents.
Insofar as this opinion pertains to matters governed by the laws of the
Commonwealth of Massachusetts, we are relying, with your consent, upon the
opinion of Bingham Dana LLP dated January 12, 1999, which opinion is
satisfactory in substance and form to us.

          Based upon the foregoing, it is our opinion that:

          (1)      The Trust is duly organized and existing under the Trust's
                   Declaration of Trust and the laws of the Commonwealth of
                   Massachusetts as a voluntary association with transferable
                   shares of beneficial interest commonly referred to as a
                   "Massachusetts business trust."

          (2)      The Shares, when issued and sold in accordance with the
                   Trust's Declaration and By-Laws and for the consideration
                   described in the Agreement and Plan of Reorganization, will
                   be legally issued, fully paid and non-assessable, except that
                   shareholders of the Acquiring Fund may under certain
                   circumstances be held personally liable for its obligations.

          We hereby consent to the filing of this opinion as Exhibit 11(a) to
the Registration Statement and to the references to us under the caption "Legal
Opinions" in the Joint Proxy Statement - Prospectus contained in the
Registration Statement.

                            Respectfully submitted,



                            VEDDER, PRICE, KAUFMAN & KAMMHOLZ
