EXHIBIT 1
Letter to the Fund
Transmitted December 14, 2009



David J. Shladovsky, Secretary and Chief Compliance Officer						December 14, 2009
Kayne Anderson MLP Investment Company
717 Texas Avenue, Suite 3100
Houston, Texas 77002

	Re:	Kayne Anderson MLP Investment Company ("KYN" or the "Fund")

Mr. Shladovsky:
Karpus Management, Inc. ("Karpus") represents beneficial shareholder ownership of 946 shares or 31.5% of the Kayne Anderson MLP Investment Company preferred shares, cusip no. 486606205 ("KYN Preferred Shares").

Pursuant to the Fund's DEF 14A filed on April 29, 2009, Karpus believes that the term of one (1) KYN Preferred Share director currently serving on the KYN Board expires at the 2010 Annual Meeting. This letter shall serve as notification that Karpus hereby nominates one (1) director nominee to be solely elected by the holders of the KYN preferred shareholders at the next annual meeting of shareholders anticipated to be held in June 2010 ("2010 Annual Meeting").

To the extent that more than one (1) vacancy exists on the KYN Board to be elected solely by the KYN Preferred shareholders and to be filled by election at the 2010 annual meeting or KYN increases the size of the KYN Board above its existing size, Karpus reserves the right to nominate such additional preferred share nominees to be elected to the KYN Board at the 2010 Annual Meeting. Additionally, if this Notice shall be deemed for any reason to be ineffective with respect to the nomination of the Nominee indicated below, or if the indicated Nominee shall be unable to serve for any reason, this Notice shall continue to be effective with respect to the remaining Nominee(s) and as to any replacement Nominee(s) selected by Karpus.

Karpus is submitting its director nominee because we feel that the KYN preferred shareholders should have effective representation on the Fund's Board. We are disappointed that the Fund has not publicly announced any intent to consider providing liquidity to its auction rate preferred shareholders, despite having completed a private placement of $110 million of senior unsecured fixed and floating rate notes that the Fund indicates will be used to repay "certain of the Company's current borrowings."

Additionally, Tortoise Energy Capital Corp., a closed-end fund with a similar investment objective to that of KYN, recently announced the intent to use proceeds from funds borrowed from its credit facility and net proceeds from the issuance of Mandatory Redeemable Preferred Shares to redeem all of its outstanding auction rate preferred shares. We do not understand why our KYN preferred shareholder director "representatives" are not considering a similar measure.

As preferred shareholders, we therefore do not feel that we are receiving adequate representation from the existing designated preferred share directors of KYN. Because of these reasons, we question the effectiveness of the current KYN preferred directors and consequently we believe that our director nominee, if elected, will more accurately represent the interests of KYN's preferred shareholders.

The information concerning the Nominee required by the Nominating Committee Charter is set forth below:

    Phillip Goldstein; Age: 64; Address: Park 80 West, 250 Pehle Avenue, Suite 708, Saddle Brook, NJ 07663; Share Ownership: N/A; Directorships/Other: Mr. Goldstein is an investment advisor and a principal of the general partner of six investment partnerships in the Bulldog Investors group of funds and is a principal of Brooklyn Capital Management LLC, the investment advisor for Insured Municipal Income Fund. He has been a director of the Mexico Equity and Income Fund since 2000, Brantley Capital Corporation since 2001, ASA Ltd since 2008 and Insured Municipal Income Fund since 2009.

Karpus does not believe that this Nominee is an "interested person" of KYN, as defined in the Investment Company Act of 1940. Further, there are no arrangements or understandings between Karpus and any nominee in connection with the nominations nor do we know of any material conflicts of interest that would prevent any nominee from acting in the best interest of the Fund. Lastly, attached is the consent of Mr. Goldstein, whereby Mr. Goldstein consents to be nominated as a director of KYN at the 2010 Annual Meeting and further consents to serve if elected.

Should you have any questions with respect to this notification or require further information, please do not hesitate to contact me at (585) 586-4680.

Sincerely,



Cody B. Bartlett Jr., CFA
Managing Director of Investments
