St. Mark's Episcopal Church, Gothic Revival church in Shreveport, United States.

St. Mark's Episcopal Church is the Gothic Revival building at 875 Cotton Street in Shreveport, listed on the National Register of Historic Places in 1991. It housed St. Mark's congregation until 1954, when the parish moved to Fairfield Avenue and Rutherford Street. The building holds an E.M. Skinner organ built in 1920, and a large Aeolian-Skinner organ was ordered in 1956.

The Episcopal congregation was founded in 1839 and held its first services under Bishop Leonidas Polk. The present building was constructed in 1954, and the parish was elevated to cathedral status in 1990.

The building housed St. Mark's until 1954, when a group of parishioners stayed behind to keep an Episcopal presence in the inner city and formed the Church of the Holy Cross. The congregation is known for a progressive stance on social issues: it is one of the few churches in North Louisiana that will marry gay couples, while keeping a traditional worship style.

The church sits at the corner of Fairfield Avenue and Rutherford Street and is easy to locate from the street. Visitors should check in advance to learn which areas are open to the public and when specific services or events take place.

The church operates Holy Cross Hope House, a program helping people experiencing homelessness in the area. This service demonstrates how the parish translates its faith into practical support for the community.
