Sandy Hook is a home rule-class city beside the Little Sandy River in Elliott County, Kentucky, in the United States.^[4] The population was 675 at the 2010 census.^[5]

Sandy Hook is the county seat of Elliott County, which is a dry county. It is illegal to sell alcohol within the city. The Little Sandy Correctional Complex, a medium-security prison operated by the Kentucky Department of Corrections, is located 6 miles (10 km) northeast of Sandy Hook.

The head of navigation on the Little Sandy River was first settled in the 1820s. By the time of its establishment by the state legislature in 1850, it was known as "Sandy Hook" for the fishhook-shaped bend in the river at that point.^[6]

It was chosen as the seat of the newly established Elliott County over nearby Newfoundland in 1869, owing to a generous donation of land for public buildings by resident James Hunter. In 1872, the city was incorporated as "Martinsburg" in honor of Congressman John P. Martin. The priority of another Martinsburg, Kentucky, meant that the post office (est. 1874) had to be named "Sandy Hook". The city resumed the name shortly after^[6] and was reincorporated as "Sandy Hook" in 1888.^[1]
