St. Mark's Cathedral, Episcopal cathedral in Shreveport, United States

St. Mark's Cathedral is an Episcopal cathedral at Fairfield Avenue and Rutherford Street in Shreveport, Louisiana, completed in 1954 in Gothic Revival style. It is the seat of the Diocese of Western Louisiana, a status it received on July 7, 1990. The parish traces its founding to a March 1839 liturgy celebrated by Bishop Leonidas Polk.

The first Episcopal service in Shreveport was held in March 1839 by Bishop Leonidas Polk, and that liturgy is counted as the founding of St. Mark's Church. The parish met on Fannin Street, then from 1905 at Cotton Street and Texas Avenue, a building now the Church of the Holy Cross. The present church at Fairfield Avenue and Rutherford Street was completed in 1954 and became the diocesan cathedral on July 7, 1990.

The parish takes its name from Saint Mark the Evangelist, and its first liturgy was celebrated by Bishop Leonidas Polk in March 1839, a date treated as the founding day. The cathedral congregation has long supported St. Mark's Cathedral School, which began as a day school in September 1953.

The cathedral stands at the corner of Fairfield Avenue and Rutherford Street, where the present building was completed in 1954. Its affiliated school occupies the same Fairfield Avenue site, opened there in January 1954. Visitors arriving by car should orient themselves by these two cross streets before setting out.

St. Mark's Day School was founded in September 1953 by a committee of parishioners as an early childhood program, and it moved to its Fairfield Avenue site when that building opened in January 1954. It later grew into St. Mark's Cathedral School, teaching three-year-olds through eighth grade.
