The '''Smart Game Format''' ('''SGF''') is a [[file format]] used for storing records of [[board game]]s. [[Go (game)|Go]] is the game that is most commonly represented in this format and is the [[default (computer science)|default]]. SGF was originally created under a different name by '''Anders Kierulf''' for his SmartGO program.

The main purposes of SGF are to store records of played games and to provide features for storing annotated and analyzed games (e.g. board markup, [[Variation (game tree)|variation]]s). It is a text-only, tree-based format.

Most [[Internet Go server]]s and [[Go software]] from 1990 support this format.
