The ATP 250 tournaments are the lowest tier of annual men's tennis tournaments on the main ATP Tour, after the four Grand Slam tournaments, ATP Finals, ATP 1000 tournaments, and ATP 500 tournaments. The winners of each tournament are awarded 250 ranking points—which accounts for the name of the series.

As of 2025, the series included 30 tournaments after the retirement of four tournaments (Atlanta, Córdoba, Metz and Marseille), the downgrade of two in 2025 (Estoril for a year, and Newport) and the upgrade of three tournaments to the 500 level (Dallas, Doha and Munich). Draws usually consist of 28 for singles, with Brisbane International (32) and Winston-Salem Open (48) being the only exceptions. Doubles draws consist of 16 teams.

Thomas Muster holds the record for most singles titles at 26, while Mike Bryan holds the record for most doubles titles won with 46.
