KW United is a Canadian semi-professional soccer club based in Waterloo, Ontario that plays in the League1 Ontario men's and women's divisions. Their home stadium is Warrior Field at the University of Waterloo.
Waterloo United, a youth club founded in 1971, launched their semi-professional side in League1 Ontario in 2021. In 2022, Waterloo United partnered with Borussia Dortmund, becoming part of their BVB International Academy North America program, rebranding the League1 Ontario club to BVB International Academy Waterloo from 2022 through 2024, before ending the partnership in 2025 and re-verting to the Waterloo United name. In 2026, they announced they would partner with Kitchener TFC to jointly run the semi-professional team, re-branding the semi-professional team to KW United for the 2027 season.
The club was founded in 1971 as the Waterloo Minor Soccer Club. In 2011, the club rebranded as Waterloo United. In 2019, the club was awarded the Canada Soccer National Youth Club Licence by the Canadian Soccer Association.
In 2020, the team was to begin play with a U21 team in the League1 Ontario Reserve Division, however, the season was cancelled due to the COVID-19 pandemic. In 2021, lining up with the club's 50th anniversary, they added a team in the League1 Ontario main division. The club also added a team in the League1 Ontario women's division for the 2021 season. The city of Guelph also added men's and women's teams in 2021, setting up a natural local rivalry for the two clubs. However, due to the COVID-19 pandemic, Waterloo deferred their entrance to the League1 Ontario top division until 2022.


In 2022, the club struck an affiliation agreement with German club Borussia Dortmund. As part of the agreement, the League1 Ontario teams competed under the name BVB IA Waterloo. In February 2025, the club returned to using the Waterloo name for their League1 Ontario teams, while the youth sides retained the BVB branding. In August 2025, the club fully ended the partnership, returning to using the Waterloo United branding for the whole club.
In March 2026, Waterloo United announced a partnership with Kitchener SC to jointly support the Ontario Premier League (re-branded from League1 Ontario in 2026) team, with the team to announce a re-brand in 2027 (they will continue to use the Waterloo United name for 2026 - both clubs would still operate their own separate youth programs). In October 2026, it was revealed that the team would be known as K-W United.
