Bersirc is a discontinued open-source Internet Relay Chat client for the Microsoft Windows operating system.

[3] Bersirc features connections to multiple servers, a finger client, DCC File Transfers and Chat, Smart Paste, Object Pascal Scripting, Internet Time Support (Swatch Netbeats), Channel Lists, Favorite Channels list, Ident Server, AutoJoin on Invite, AutoRejoin on Kick, configurable date formats, an ICQ-like notify list, advanced filtering, a configurable user interface, and a built in IRC user guide.

[7] Bersirc was originally written in Delphi by Jamie Frater in 1999 as a Windows-only IRC client,[2] comparable to HydraIRC and Klient.

The German website Winfuture referred to version 2.2.13 as a "great free alternative to the popular shareware IRC client mIRC.
