Jenner & Block is a U.S. law firm with offices in Chicago, New York, Los Angeles, and Washington, DC. Approximately 450 attorneys serve a wide range of clients in corporate litigation, business transactions, and in the public sector. Jerold S. Solovy was the longtime Chair of the firm, but on Sept. 26, 2007, the firm announced that Solovy would step down from that post after 17 years in favor of Anton "Tony" Valukas. The voting partners did not reelect Solovy to the firm's Policy Committee in 2008. Susan C. Levy became Managing Partner on June 30, 2008. Thomas J. Perrelli was the managing partner for the Washington, DC office which was established in 1982.

Founded as a partnership in 1914, the firm has undergone several name changes. During the period from the 1920s to the 1950s, the firm was known as Johnston, Thompson, Raymond & Mayer, led by a leading Chicago trial lawyer, Edward R. Johnston, and a former Chief Justice of the Illinois Supreme Court, Floyd E. Thompson. Their early successes included defending Preston Tucker's company, Tucker Corp., against corporate financing fraud charges. After Albert E. Jenner became a name partner in 1955, he helped the firm cement its reputation as a pro bono powerhouse (according to the editors of The American Lawyer in 2003) and established Jenner & Block's longstanding relationship representing General Dynamics. Samuel W. Block was made a name partner in 1964, and the firm has been known as "Jenner & Block" ever since.

Among some of the distinguished lawyers who have practiced at Jenner & Block are Supreme Court Justice John Paul Stevens, Judge Phillip Tone of the U.S. Court of Appeals for the Seventh Circuit, and two former U.S. Attorneys for the Northern District of Illinois, Thomas P. Sullivan and Anton Valukas.

Jenner's main offices in Chicago are currently located at 353 North Clark. The main office was previously located at 330 North Wabash until October 2009.
