Halsted Lockwood Ritter was a United States district judge of the United States District Court for the Southern District of Florida. He was the thirteenth individual to be impeached by the United States House of Representatives and the fourth individual to be convicted and removed from office in an impeachment trial before the United States Senate. He was also the last federal official to be impeached by the House of Representatives until Harry E. Claiborne, when he was impeached and removed from office by the Senate for tax evasion in 1986.

In the United States, federal impeachment is the process by which the House of Representatives charges the president, vice president, or another civil federal officer for alleged misconduct. The House can impeach an individual with a simple majority of the present members or other criteria adopted by the House according to Article One, Section 2, Clause 5 of the U.S. Constitution.
