St. Mark's Pro-Cathedral is an Episcopal Church building located in Hastings, Nebraska, United States.

John W. Greenwood arrived in Hastings in 1880 to organize the parish, St. Mark's was an unorganized mission with no property or building, and with very few members.

[2] The Daughters of Saint Mark's suggested that a new church be built in memory of the rector’s late wife Jessie Hornbrook Young.

In 1912, they raised $10,000 after Bishop George Beecher suggested that Hastings be made a see city and the new church become the cathedral.

The Edward R. Green Company completed the construction; the total spent to build the church amounted to $125,000.

[5] The plan of the building has characteristics of English Gothic churches, including an emphasis on length, a moderately pitched roof, and a tower at the crossing.

The roof structure, described in the National Register nomination as "an elaborate beam system of king post trusses", is exposed in the ceiling.
