Where can I find a treaty to which the United States is a party?

The Law Library of Congress provides digital access to Charles I. Bevans’s Treaties and Other International Agreements of the United States of America, 1776-1949, which includes copies of the English version (or English translation) of multilateral treaties to which the United States was a party. Digital copies of the remaining volumes (5-12), which include the bilateral treaties to which the United States was a party during this period, will be added in the near future.

The Law Library's Treaties page also links to the United States Department of State’s Treaties and Other International Acts webpage, which includes PDF copies of the executed English-language original of each published international agreement (and other important documents) for published international agreements entered into from 1996 to the present.

The Treaties and Other International Acts series (also known as TIAS), which is “the official print publication format for treaties and agreements that have entered into force for [the] U.S.,” was published in print from 1945 to 2006, and has been made available online.

Information about treaties considered in Congress from 1973 to the present, and the full text of treaties from 1995 to the present, can also be found on Congress.gov. Refer to Congress.gov's "About Treaties" page for information about how to search the treaty collection.
