The ATP Auckland Open, commonly known by its sponsored name ASB Classic, is a professional men's tennis tournament in Auckland, New Zealand. The tournament is played at the ASB Tennis Centre, in Parnell. It is part of the ATP World Tour 250 series of the Association of Tennis Professionals (ATP) World Tour. The tournament is held annually in January a week before the first Grand Slam tournament of the season, the Australian Open.

The ASB Classic returned in 2023 after the 2021 and 2022 events were cancelled due to the COVID-19 pandemic causing travel restrictions for international visitors to New Zealand.
