Form 10-K for the year ended December 31, 2008

File No. 001-33859

Dear Ms. Crittendon:

We are providing the responses to your comments of January 19, 2010, to the United States 12 Month Oil Fund, LP (“US12OF”), on US12OF’s Form 10-K for the year ended December 31, 2008. Each of your comments is set forth below, followed by US12OF’s response.

Form 10-K for the year ended December 31, 2008

How Does US12OF Operate?, page 2

1.	We note your response to previous comment 2; however, we continue to believe that your portfolio composition is material to an investor’s understanding of the fund’s business. It appears that disclosing your portfolio composition in percentage terms rather than dollar amounts could provide the appropriate information and avoid the concerns expressed in your response regarding volatility in the size of the fund. Disclosure of your portfolio holdings as of the end of each quarter in the fiscal year may address concerns about the limited nature of year-end only disclosure. In addition, we note that such disclosure would appear to be consistent with your financial statement disclosure requirements. Please confirm that you will provide disclosure about your portfolio as previously requested or, alternatively, provide a more detailed analysis regarding the materiality of this disclosure.

	Response: US12OF confirms that it will include disclosure in its quarterly and annual reports on Form 10-Q and 10-K, as the case may be, consistent with your request. Specifically, US12OF will include the following disclosure in the section entitled, “Management’s Discussion and Analysis of Financial Condition and Results of Operations”:

“On [date], US12OF’s portfolio consisted of [ ] Crude Oil Futures Contracts traded on the NYMEX. For a list of US12OF’s current holdings, please see US12OF’s website at www.unitedstates12monthoilfund.com.”

To the extent US12OF holds other crude oil-related interests, other than futures contracts traded on NYMEX, it will disclose these holdings in a similar manner.

We hope that you will find this response satisfactory. If you have questions or further comments, please call the undersigned at 510.522.9600.
