AS50 is a model name that has been applied to several distinct hollow body electric guitar models produced by Ibanez since 1980. Each version is an affordable model in the AS line.

- AS50 (1990–1991), made in Korea by Yoojin, set-in neck, narrow headstock
- AS50 (1998–1999), made in Korea by Cort, bolt-on neck, wide headstock
