The 223 series (223系, 223-kei) is a suburban electric multiple unit (EMU) train type operated by the West Japan Railway Company (JR-West) in the Kansai region, Chūgoku region and Shikoku region of Japan. Multiple batches of the model have been built with varying differences (particularly motor output control), although the overall general appearance remains similar.

Design of the rolling stock was an improved adaptation of the 221 series, with three pairs of doors per side per car and a transverse seating layout. Production of the train type first began in 1993.^[1]
