Old Indian River County Courthouse, National Register site in Vero Beach, Florida.

The Old Indian River County Courthouse is a Masonry Vernacular and Art Moderne building at 2145 14th Avenue in Vero Beach, Florida. Architect W.H. Garns designed it, and it was constructed from April 1936 to March 1937. After the county moved its courthouse to 2000 16th Avenue, the building became the Courthouse Executive Center.

The building was designed by architect W.H. Garns and built between 1936 and 1937 with funding from the Public Works Administration during the Great Depression. Its construction was part of federal programs aimed at creating jobs and modernizing regional infrastructure during this economic crisis.

The courthouse served as the center for legal matters and civic activities in Indian River County for generations. Its role as a public building made it a gathering point where residents conducted official business and witnessed community affairs.

The courthouse is centrally located in Vero Beach and easy to find on 14th Avenue with its distinctive three-story structure. Since the building now functions as an administrative center, visiting hours follow standard office hours and entry may be subject to building policies.

The building's 1936–1937 construction followed James T. Vocelle's 1933 and 1934 requests for Public Works Administration money for the newly formed county. The federal grant, not state resources, paid for the courthouse; it was added to the National Register on July 19, 1999.
