The Yokosuka R2Y Keiun (景雲 - "Cirrus Cloud") was a prototype reconnaissance aircraft built in Japan late in World War II.

Design and development
Commissioned for the Imperial Japanese Navy after the R1Y design was cancelled due to its disappointing performance estimates, the R2Y used coupled engines driving a single propeller and also featured a tricycle undercarriage.
Completed in April 1945, the prototype made a short flight on 8 May, but was destroyed in a US air raid only a few days later, thus ending development.
A proposal was also made to develop the R2Y into a turbojet-powered light bomber by replacing its piston engines with two Mitsubishi Ne-330s. Designated the R2Y2 Keiun-Kai, the prototype was begun but never completed.
