There are three church buildings in Cromarty, two of which are used for regular worship by the congregations of Cromarty Parish Church of Scotland and St Regulus Scottish Episcopal Church. The East Church is currently closed for restoration.

East Church (on Church Street)
The East Church, dating from pre-Reformation times, was the old parish church in Cromarty. In 1998 ownership was transferred to the Scottish Redundant Churches Trust and — with the approval of the Trust and the Kirk Session — used for occasional services during the summer months and for special events. The East Church featured in the BBC series 'Restoration Village' (2006). Funding from the Heritage Lottery Fund, Historic Scotland and The Highland Council has made possible the current major restoration project.

The West Church (on the High Street)
The West Church was built by the Free Church of Scotland congregation after the Disruption of 1843. Following the union of the Free Church with the Church of Scotland in 1929, both the East and West church buildings were used for worship. Since the 1990s the West Church has been designated as the parish church. Services are held on Sunday mornings at 11.30am.

St Regulus Church (on Church Street)
The Scottish Episcopal congregation in Cromarty meets in St Regulus Church. Sunday worship is held at 9.45am. Both St Regulus and the West Church are used as venues for shared services, such as joint youth services and the World Day of Prayer service.
