APc-1-class small coastal transports were a troopship design used during World War 2 for the United States Navy (USN).

The USN Chief of Naval Operations gave the order for the construction of 50 AMc coastal minesweepers, AMc-150–AMc-199 on January 19, 1942.

Then Chief of Naval Operations issued a request that the 50 ships be constructed as "raider transports, AP," for use in the South Pacific War on April 13, 1942.

Of the many APc-1-class small coastal transports built, ten ships, APc-85 to APc-94, were transferred to work in the United States Atlantic Fleet.

Many of the APc transport ships were built by small shipyards and boatyards that switched from yacht, sailboat and powerboat building to military construction.
