The Mexican Open is an ATP Tour tennis tournament played on outdoor hard courts, and held annually in late February at the Fairmont Acapulco Princess in Acapulco, Mexico. It was played on outdoor red clay courts until 2013. The change to hard courts was introduced in 2014. The Mexican Open is part of the ATP Tour 500 series on the ATP Tour.

The tournament was introduced on the ATP Tour in 1993, and began on the WTA Tour in 2001. It was held in Mexico City from 1993 to 1998, and once more in 2000, before being relocated to Acapulco in 2001. It was the closing leg of the four-ATP tournament Golden Swing. 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 pear trophy.
