The Trinity Episcopal Church is a historic church in Mobile, Alabama. It was completed in 1857 to serve as the worship place of the second Episcopal congregation in the city. It took four years to complete the structure, with its cornerstone having been laid in 1853. Some say that the yellow fever outbreak in the city affected its construction process.

The Trinity Episcopal Church was built in the Gothic Revival style after the design of architect Henry Dudley and Frank Wills. It became the first large church in the said architectural style in the state after its completion.

The Trinity Episcopal Church is currently a part of the National Register of Historic Places. It has been nominated to become a National Historic Landmark, but since it was moved from its original location in the St. Anthony and Jackson Streets to its present location in Dauphin Street, it failed to get the designation.
