Lime Rock is a village and historic district (listed as Lime Rock Historic District) in the town of Salisbury, Connecticut, United States, situated on the Salmon Kill.

[citation needed] Formerly known as "The Hollow",[2] Lime Rock became a center of the iron industry with the establishment by Thomas Lamb of a forge in the village around 1734.

Senator William Henry Barnum, the chief executive of Barnum and Richardson and longest serving Chairman of the Democratic National Committee, resided in Lime Rock, and was the founder of Trinity Episcopal Church Trinity Lime Rock.

He, along with many other personages of the area's historic iron industry, is buried in the Lime Rock Cemetery.
