The Schleicher ASK 23 is a single-seat Club Class sailplane that was built by the German manufacturer Alexander Schleicher GmbH & Co.

It was the last gilder 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 nose wheel, a fixed main-wheel and a tail-skid or optional tail wheel.

It first flew in October 1983. The first version allowed a very heavy pilot to fly, with originally a 140 kg maximum cockpit weight. This was reduced to 120 kg in the later 'B' version. 51 of the original version were built and 102 of the 'B' version.
