Write a letter to Oprah Winfrey by sending an addressed letter to her at The Lot, the studio at which her offices are located in West Hollywood, California. The address for the studios is The Lot, 1041 North Formosa Avenue, West Hollywood, CA, 90046. You can also write to her by writing to her magazine, O, at 300 West 57th Street, 36th Floor, New York, New York 10019.
Oprah moved her studios and operation from Chicago to Hollywood in 2015, so you should not write to any addresses you find for Oprah in Chicago, though letters sent there may be forwarded.
Consider sending an email rather than a physical letter. In 2011, Oprah gave out her personal email address and promised to read and reply to as many emails as she can. That email address is firstname.lastname@example.org.
Contact Oprah by writing to her at her talent agency, William Morris Endeavor, which is based at 9601 Wilshire Blvd., Beverly Hills, CA 90210 USA. Oprah Winfrey is most well-known for her television show, "The Oprah Winfrey Show," which ran from 1986 and 2011.
