Tuen Mun (Chinese: 屯門) is an MTR Light Rail stop which belongs to zone 2.

This Light Rail stop is located above Pui To Road and Ho Pong Street and north of Tuen Mun Park.

It provides service for nearby residents[vague] and is an interchange station for the Tuen Ma line, formerly known as the West Rail line.

On 1 August 2003, San Fat stop was renamed Tuen Mun stop (in preparation for the opening of the West Rail line Tuen Mun station later that year).

On 30 August the same year, the elevated platforms officially commenced service, although some Light Rail vehicles had been using the westbound platform from one week before.
