The Maharashtra Open (known as Tata Open Maharashtra for sponsorship reasons) was an annual men's ATP Tour 250 Tennis championship since 1996. It was held in Pune (since 2018) and was part of the ATP Tour, before it was moved to Hong Kong in 2024.
Maharashtra State Lawn Tennis Association (MSLTA), the governing body of Tennis in Maharashtra state annually organised at Shree Shiv Chhatrapati Sports Complex. It was a hard court championship and men's singles and doubles matches were organised.
The inaugural event was held in New Delhi. It was then shifted to Chennai since its second edition, and from there it was moved to Pune in 2018, where it is held in January. The tournament is owned and organized by RISE Worldwide. It was the only tour level tennis event currently held in India. It was also the only South Asia's ATP tour professional tennis event.
Tallon Griekspoor of Netherlands was the last title holder in singles and Belgium’s Sander Gillé and Joran Vliegen were the holders in doubles in 2023.
