Edogawa Maru (Kanji:江戸川丸) was a 6,968-ton Japanese Type 2A Wartime Standard cargo ship that was sunk by USS Sunfish on 18 November 1944 with 2,114 lives lost.

Edogawa Maru sailed as part of convoy MI-27 with seven other ships from Moji to Miri, Borneo, on 15 November 1944.

[1] Nevertheless, a group of three submarines—Peto, Spadefish, and Sunfish—found and attacked the convoy on the night of 17/18 November.

At 22:00 a torpedo from Sunfish struck and crippled Edogawa Maru.

In the early hours of 18 November a second torpedo from Sunfish finished off Edogawa Maru.
