The Catholic Parish of the Holy Trinity is a Roman Catholic faith community serving the town of Westhill, Aberdeenshire, and the surrounding area. It is part of the Roman Catholic Diocese of Aberdeen. The parish is unique in that it functions as part of a shared ecumenical partnership. Rather than maintaining a standalone building, the Catholic congregation shares a multi-purpose church building with the local Church of Scotland and formerly Scottish Episcopal congregations. The shared facility is a welcoming environment known for its peaceful atmosphere and communal spirit.
The congregation gathers for worship at Trinity Church on Westhill Drive, utilising a shared facility originally built in 1981 and expanded in 2003 and 2025. Sunday Mass is celebrated weekly at 9:00 am in the main hall. Weekday services are held in the building’s smaller, intimate chapel. The parish organises active community and youth initiatives throughout the year.
