Gary City Center Historic District, Historic district in downtown Gary, United States.

Gary City Center Historic District covers 60 contributing buildings and 2 sites in downtown Gary, Indiana, developed between about 1906 and 1944. It includes City Hall and the Superior Courthouse (1927), the second Gary Land Company Building (c. 1907), the Gary State Bank Building (1929), Hotel Gary (1926), the YWCA Building (1922), and the former U.S. Post Office Building (1936). Styles range from Tudor Revival to Late Gothic Revival and Classical Revival.

The district formed between 1906 and 1944 and was shaped by buildings that document the city's growth during this period. Major structures like City Hall, the courthouse, and the state bank were built during these years and record the city's economic importance at that time.

The district's name comes from its position in downtown Gary, a planned steel city. Among its buildings, the 1926 Hotel Gary and the 1929 Gary State Bank Building show the commercial architecture of the 1920s, while the 1922 YWCA Building and the 1927 City Hall and Superior Courthouse represent civic and social life of the same decades.

The district lies in downtown Gary, about 1 km from the city centre, on flat ground at roughly 183 m above sea level. Its 60 contributing buildings and 2 sites sit close together, so the blocks can be covered on foot. Look for the 1927 City Hall and Superior Courthouse and the 1936 former U.S. Post Office Building as orientation points.

Within the district stand the ruins of a Methodist church from 1926, now a quiet witness to lost architecture. This decayed building stands apart from the carefully maintained structures and tells a different story about the changes the city has experienced.
