Elkins Hall is a historic administrative building located on the north side of the campus of Nicholls State University fronting Bayou Lafourche.

Originally, it was called simply the Main Building, and housed the college's administrative offices, classrooms, laboratories, cafeteria, bookstore, and library.

The building was named for Dr. Charles Calvert Elkins (1900–1963), founding dean of Francis T. Nicholls Junior College.

[7] In keeping with the Classical Revival style, the building is two rooms deep and features a rectangular floorplan and gable-fronted roof.

The front of the building includes a white two-story portico with a triangular pediment featuring a circular window, supported by four columns on square bases.
