The Schleicher ASK 23 is a single-seat Club Class sailplane that was built by the German manufacturer Alexander Schleicher &Co. It was the last glider to be designed by Rudolf Kaiser. It is an early solo sailplane with docile handling, and so it was a successor to the Schleicher Ka 8 and ASK 18. It is also the single-seater counterpart of the two-seater Schleicher ASK 21 with a similar cockpit layout.
It uses glass-fibre reinforced plastic and 'honeycomb' as its main constructional materials. It has no flaps, a fixed nose wheel, a fixed main-wheel and a tail wheel. The first ASK 23 flew in October 1983.
