2021–22 Western United FC season

The 2021–22 season was the third in the history of Western United Football Club. In addition to the domestic league, Western United also competed in the FFA Cup for the first time.

They finished third in the regular season and then won the Championship, beating holders Melbourne City in the Grand Final.

The season was documented in the docuseries United.

Background
Western United's 2020–21 campaign had seen an eight-game losing streak and a lack of creativity lead to a disappointing tenth-place finish in the league, the club's lowest in their history forcing them to play in the 2021 FFA Cup seventh preliminary round against Newcastle Jets. Three days after their league finish on 8 June 2021, the club parted ways with their head coach Marko Rudan who was their manager since their first season in 2019–20.

Matches
The league fixtures were announced on 23 September 2021.
