The Mexican Open (currently sponsored by Telcel and HSBC and called the Abierto Mexicano Telcel presented by HSBC) is a professional tennis tournament played on outdoor hard courts, and usually held annually in late February and early March at the Arena GNP Seguros[1] since 2022 and previously at the Fairmont Acapulco Princess, both in Acapulco, Mexico.

Starting in 2014, the Mexican Open's surface changed from clay to hard courts, serving as a lead-up to the first ATP Tour Masters 1000 event of the season in Indian Wells, United States.

The winner traditionally receives a giant silver gourd trophy.

On the women's side, Amanda Coetzer (2001, 2003), Flavia Pennetta (2005, 2008), Venus Williams (2009–10), Sara Errani (2012–13), and Lesia Tsurenko (2017–18) co-hold the record for most singles titles (two), Williams, Errani and Tsurenko being the only players to score two straight wins in Mexico.

In the women's doubles, María José Martínez Sánchez (2001, 2008–09) is the one holding the most titles (three) and shares with Nuria Llagostera Vives (2008–09) the record for most consecutive wins (two).
