Hampshire 3 is an English level 12 Rugby Union league for teams based in Hampshire and the Isle of Wight. Hampshire 2, Hampshire 3 and Hampshire 4 are also known as Hampshire Merit Tables. Promoted teams move up to Hampshire 2 and relegated teams drop to Hampshire 4.
The teams competing in 2021-22 achieved their places in the league based on performances in 2019-20, the 'previous season' column in the table below refers to that season not 2020-21.
A combined Millbrook / Stoneham side were Hampshire 3 champions in 2019-20, they were replaced by Millbrook 2XV for the current season. Trojans II replaced Trojans III.
On 30 October the RFU announced that a decision had been taken to cancel Adult Competitive Leagues (National League 1 and below) for the 2020/21 season meaning Hampshire 3 was not contested.
