Lichess Rated Standard Chess Games Dataset
Dataset Description
6,771,826,271 standard rated games, played on lichess.org, updated monthly from the database dumps.
This version of the data is meant for data analysis. If you need PGN files you can find those here. That said, once you have a subset of interest, it is trivial to convert it back to PGN as shown in the Dataset Usage… See the full description on the dataset page: https://huggingface.co/datasets/Lichess/standard-chess-games.chess_gamesDataset descriptions:

Lichess Broadcasts Dataset
Dataset Description
931,021 chess games from chess tournaments tracked using Lichess Broadcasts.
Lichess Broadcasts show live games as they unfold with new moves arriving in real time. They are built to connect to the live-updating PGN file produced by DGT boards but can work with other sources as well.
Broadcasts are organized in "tournaments" and "rounds."

chessgamestitled-tuesday-chess-gamesThis dataset includes chess games played in the Chess.com "Titled Tuesday" events from July 2022 to December 2023. The games in the dataset were played by titled players
who ranked 1-25 in at least one tournament. Since game documents are organized around players and there are duplicate games, the dataset is more suitable for the player-centric analyses.
This GitHub repository contains scripts for scraping the data from Chess.com

Chess Games Dataset
This dataset is a compact, ML-oriented chess game dataset generated from
angeluriot/chess_games
plus additional 2025 games extracted from
Lumbras Giga Base.
It keeps only the move sequence in UCI notation, a derived minimum Elo field,
and a source label. This makes the dataset smaller and simpler to consume than
the base dataset when the downstream task only needs legal move sequences and a
coarse player-strength signal.
