USCGC Edgar Culbertson (WPC-1137) is the United States Coast Guard's 37th Sentinel-class cutter, and the second of three to be homeported in Galveston, Texas.

[3][4] Like her sister ships, Edgar Culbertson is designed to perform search and rescue missions, port security, and the interception of smugglers.

Edgar Culbertson was delivered to the Coast Guard, for her acceptance trials, in Key West, on February 6, 2020.

[2][8] In 2010, Charles "Skip" W. Bowen, who was then the United States Coast Guard's most senior non-commissioned officer, proposed that all 58 cutters in the Sentinel class should be named after enlisted sailors in the Coast Guard, or one of its precursor services, who were recognized for their heroism.

[11] Culbertson and two other Coast Guard sailors saw three teenage boys at the end of a long pier, on Lake Superior, when a storm had whipped up 20 feet (6.1 m) waves.
