USS SC-26, until July 1920 known as USS Submarine Chaser No. 26 or USS S.C. 26, was an SC-1-class submarine chaser built for the United States Navy during the First World War.

SC-26 was a wooden-hulled 110-foot (34 m) submarine chaser built at the New York Navy Yard at Brooklyn, New York. She was commissioned on 19 October 1917 as USS Submarine Chaser No. 26, abbreviated at the time as USS S.C. 26.

When the U.S. Navy adopted its modern hull number system on 17 July 1920, Submarine Chaser No. 26 was classified as SC-26 and her name was shortened to USS SC-26.

On 20 July 1921, the Navy sold SC-26 to Henry A. Hitner's Sons Company of Philadelphia, Pennsylvania.

The USS SC-1-class submarine chasers, including USS SC-26, represented a significant advancement in the U.S. Navy's approach to anti-submarine warfare. While many of these vessels had short service lives due to rapid technological advancements, their contributions laid the groundwork for future developments in naval warfare and submarine detection techniques.
