Kazaa Lite (sometimes Kazaa Light) is a free P2P file sharing software application. Kazaa Lite is a spin-off of the Kazaa application. Kazaa Lite contains no ads, a built in privacy firewall called PeerGuardian, and other features intended to improve on the original Kazaa.

Kazaa Lite also sports a very good reputation in the P2P community for the committment and ethics of its users. Kazaa Lite users tend not to "leech" (download files from others without sharing their own) or post fake files, two key things that undermine the quality of any P2P file sharing system. The owners of the original Kazaa Media Desktop, Sharman Networks, have pushed to shut down Kazaa Lite, claiming that the client is an unauthorized derivative work. However, given the decentralized nature of P2P systems, disabling Kazaa Lite may be impossible to accomplish technically. Several once-popular free download locations for Kazaa Lite, including www.kazaalite.tk, have been shut down, but others remain.
