USC&GS Thomas R. Gedney, originally USCS Thomas R. Gedney, was a survey ship in service in the United States Coast Survey from 1875 to 1878 and in the United States Coast and Geodetic Survey from 1878 to 1915. In October 1903, Thomas R. Gedney was operating in Alaska when found the steamer Farallon anchored in Frederick Sound with a broken propeller shaft and more than 100 passengers were on board. She towed Farallon to Tonka Cannery in Wrangell Narrows, where Farallon transferred her passengers and got further assistance. Thomas R. Gedney was retired from service later in 1915.
