PGN Mentor is a long-running website that maintains a curated library of PGN game files, organized into convenient collections by player, opening system, and tournament. Rather than a searchable database, it functions as a download repository — ideal for loading specific collections into a chess GUI or database program for offline study.

The player files cover most of the world's top grandmasters with complete or near-complete career games. Opening files provide large collections for specific variations, useful for studying a particular line statistically. Tournament files cover major events from recent and historical championships.

All downloads are free and require no registration. PGN Mentor is particularly useful for players who prefer to work in desktop software like ChessBase or Scid and want pre-organized game sets rather than downloading from a live database.
