Griffith is a town in North and St. John[7] townships in Lake County, Indiana, United States.

[11] In 2018, citizens of Griffith voted by a margin of 98% to 2% to leave Calumet Township, in part because of the high property taxes they pay to the township, which also includes Gary, relative to the services received.

The town's boundaries encompass part of the ancient Calumet shorelines of Lake Michigan.

[16] Griffith borders the town of Highland to the west, the city of Hammond to the northwest, the city of Gary to the northeast, the town of Schererville to the south, and unincorporated Calumet Township to the east.

[18] St. Mary Catholic Elementary & Junior High School is located in Griffith.

29.4% of all households were made up of individuals, and 10.9% had someone living alone who was 65 years of age or older.

26.3% of all households were made up of individuals, and 7.6% had someone living alone who was 65 years of age or older.

Cline Avenue runs through Griffith north to East Chicago.

Interstate 65, The Borman Expressway, The Indiana Toll Road US 30 and US 41 are all short drives from Griffth.

[21] Broad Street, the major north–south road through Griffith, used to be designated Indiana State Route 73.

Technically, a part of it straddled the border between St. John township and Schererville, but since the entire right of way did not reside in either, that part which did lie entirely within the borders of any designated area, were only in Griffith, and hence the appellation stuck.

Also, US 6 was removed from its route along Ridge Road at the northern terminus of SR 73 to the Borman Expressway.

Its importance diminished and its major connections removed, the Indiana legislature felt that a road that lay entirely within a single town (or at least did not have a portion that sat entirely in another town), should not be provided state funding as its primary source of upkeep.
