USS Wake (PR-3) was a United States Navy river gunboat operating on the Yangtze River. Originally commissioned as the gunboat Guam (PG-43), she was redesignated river patrol vessel PR-3 in 1928, and renamed Wake 23 January 1941. She was captured by Japan on 8 December 1941 and renamed Tatara. After her recapture in 1945, she was transferred to Chinese nationalists, who renamed her Tai Yuan. Communist forces captured her in 1949. On 1 May 1949 Tai Yuan was sunk by Nationalist aircraft in the Caishiji River.

A river gunboat is a type of gunboat adapted for river operations. River gunboats required shallow draft for river navigation. They would be armed with relatively small caliber cannons, or a mix of cannons and machine guns. If they carried more than one cannon, one might be a howitzer, for shore bombardment. They were usually not armoured. The fictional USS San Pablo described in Richard McKenna's The Sand Pebbles is an example of this class of vessel, serving on the US Navy's Yangtze Patrol. Stronger river warships with larger guns were river monitors.
