The Potez 23 was a prototype French single-engine fighter biplane designed in 1923.

The Potez 23 was built by Potez in response to the C1 fighter program issued by the STAé in 1923. The C1 fighter specification called for a speed of 240 kilometres per hour (150 mph), an armament of two forward firing machine guns, and both armored tanks and drop tanks.^{[citation needed]}

The structure was made of wooden spars,^[1] the fuselage was covered with screwed and glued plywood, and the wings, empennage, and tail were covered in canvas. Wing tethering^{[clarification needed]} is simplified and builds on the experience gained on the Potez XV.^{[citation needed]}

The aircraft did achieve the required performance and was not accepted for production. However, it was developed into the Potez 25.^{[citation needed]}
