Carolina is a village that straddles the border of the towns of Charlestown and Richmond on the Pawcatuck River in Washington County, Rhode Island, United States.

[1] It comprises 71 properties over an area of 115 acres (0.47 km2), including a former mill complex and nearby residences.

In 1802, the first wooden dam and a gristmill were built on the river at the site of the village, which was then known as Nichols Bridge.

[7] The Rhode Island Historic Preservation Commission described 19th-century Carolina as a "center for the surrounding area, including a school, a church, a post office, a bank, several stores, a blacksmith shop, and halls for meetings, lectures, and 'entertainments'.

The portion of Carolina village which is located in the town of Richmond includes a corridor of about two dozen 1-story and 1½-story cottages and other domestic buildings built between about 1840 and 1870.

John W. Hoxie established the Clearwater Trout Farm in 1877 on White Brook on land leased from Rowland G. Hazard, north of the village center.

By 1892, the White Brook Trout Hatchery was incorporated as the American Fish Culture Company with Rowland Hazard II as a minority shareholder.

Upon the death of John W. Hoxie in 1903, the R. Hazard Estate acquired full interest in Clearwater Trout Farm, and both farms were eventually merged and operated as American Fish Culture Company by the Hazard Family until its sale to the State of Rhode Island in 1995.

The 2020 United States census counted 924 people, 382 households, and 245 families in Carolina.
