The Mikura-class escort ships (御蔵型海防艦, Mikura-gata kaibōkan^?) were a class of ships in the service of the Imperial Japanese Navy during World War II.

The Japanese called these ships Kaibōkan, "ocean defence ships" (Kai = sea, ocean, Bō = defense, Kan = ship), a name used to denote a multi-purpose vessel. The eight ships of the Mikura class served as convoy escorts during World War II. They were denoted "Type B" and were the third class of Kaibokan. The Mikuras, unlike the two preceding Etorofu and Shimushu classes, were dedicated to the anti-aircraft (AA) and anti-submarine role.

The Mikura class was initially armed with 120 depth charges with six depth charge throwers and would later receive an 8 cm trench mortar. The number of AA machine guns was increased to up to eighteen. They received Type 22 and Type 13 radars, and Type 93 or Type 3 sonar in 1943-1944.

Two ships of the class probably had success against US submarines, with Mikura helping to sink USS Trigger with kaibokans CD-33 and CD-59 on March 28, 1945. Chiburi also helped sink USS Growler with destroyer Shigure and kaibokan CD-19 on 8 November 1944.
