Gadu-Gadu (Polish for "chitchat"; commonly known as GG or gg) is a Polish instant messaging client using a proprietary protocol. Gadu-Gadu is the most popular IM service in Poland, with over 15 million registered accounts and approximately 6.5 million users online daily. Gadu-Gadu’s casual gaming portal had some 500,000 active users at the end of March 2009. Users send up to 300 million messages per day.

Gadu-Gadu is financed by the display of advertisements. The developer is based in Warsaw, Poland but the company is wholly owned by the South African media giant Naspers.

Gadu-Gadu uses its own proprietary protocol. As with ICQ, users are identified by unique serial numbers. Protocol's features include status messages, file sharing, and VoIP. Users may format and embed images in messages. Since client version 6.0, an experimental secure connection^[vague] mode can be used.

The official client provides over 150 emoticons, allows grouping contacts, sending SMS and integrates with other services ran by the same company: a virtual Internet dial-up, a social networking site MojaGeneracja.pl and an internet radio Open.fm.
