Himanshu Dinesh Jain (born 6 September 1991) is an Indian professional snooker player.
Jain turned professional as one of the two qualifiers from the second Asia & Oceania event of the 2022 Q School, earning a two-year tour card for the 2022–23 and 2023–24 snooker seasons. He became the fifth Indian to make an entry into the professional circuit and the first to do so via qualification rather than their Asian or World Championship ranking.
