The Semboku 9300 series (泉北9300系, Senboku 9300-kei) is an electric multiple unit (EMU) train type operated by the private railway operator Semboku Rapid Railway on the Semboku Rapid Railway Line and Nankai Koya Line in Japan since 8 August 2023.

The trainsets are intended for service between Namba and Izumi-Chūō stations[1] on the Semboku Rapid Railway Line, as well as through services onto the Nankai Koya Line.

Based on the design of the Nankai 8300 series,[3] the 9300 series uses LEDs for external and internal lighting, which Semboku states reduces power consumption by 50% when compared to the older 3000 series trains.

[1] The two sets were built by Kinki Sharyo and delivered in December 2022.
