The Coast Guard Bicentennial Unit Commendation is a commemorative decoration of the United States Coast Guard which was awarded to all active, reserve, auxiliary, and civilian personnel of the Coast Guard for service between the dates of June 4, 1989 and August 4, 1990.
The decoration was issued as a one-time award only and commemorates the founding of the U.S. Coast Guard in 1790, then known as the Revenue Cutter Service. The Coast Guard Bicentennial Unit Commendation was discontinued for issuance in September 1991, but Coast Guard regulations permit the continued wearing of the decoration on Coast Guard uniforms.
