PowerPlant is an object-oriented GUI toolkit, application framework and set of class libraries for Mac OS, created by Metrowerks. The framework was fairly popular at the height of the Classic Mac OS era, and was primarily used with CodeWarrior.

A new version, PowerPlant X, was introduced in 2004 as a native Carbon framework, using Carbon Events.

After Metrowerks was acquired by Motorola, then spun out as part of Freescale Semiconductor, PowerPlant and the rest of the CodeWarrior desktop development tools were discontinued. In February 2006, the PowerPlant class libraries were released as open source under the BSD license hosted on SourceForge.
