Mahesh Shrinivas Bhupathi is an Indian professional tennis player widely regarded as among the best doubles players in the world with 11 Grand Slam titles to his credit. In 1997, he became the first Indian to win a Grand Slam tournament (with Rika Hiraki). With his win at the Australian Open mixed doubles in 2006, he joined the elite group of eight tennis players who have achieved a career Grand Slam in mixed doubles.

Mahesh Bhupathi is best known as one of the top doubles players in the '90s and '00s. In 1999, Bhupathi won three doubles titles with Leander Paes, including Roland Garros and Wimbledon. He and Leander became the first doubles team to reach the finals of all four Grand Slams, the first time such a feat has been achieved in the open era and the first time since 1952. On 26 April of that year, they became the world no. 1 doubles team. Bhupathi also won the US Open mixed doubles with Ai Sugiyama of Japan.

In 2006, Bhupathi teamed with Martina Hingis in the Australian Open mixed doubles competition. Entering the tournament unseeded and as wildcards, the first-time pair defeated four seeded opponents along the way, while only dropping a single set throughout. Bhupathi and Hingis defeated the sixth-seeded team of Daniel Nestor and Elena Likhovtseva in straight sets, 6–3, 6–3, to capture the championship. It was the sixth mixed doubles Grand Slam for Bhupathi, and a first for Hingis. By winning the Australian Open, Bhupathi completed a career Grand Slam in mixed doubles.
