Matthias Nicoll (1630 – December 22, 1687), aka Nicolls, was the 6th Mayor of New York City from 1672 to 1673.
He lived in Islip, Northamptonshire and practiced law there. He was son of a minister.
In 1664 he came to the United States with Richard Nicolls. It is not known if the two were related although some sources say he was Richard's nephew.
Matthias was Richard's secretary and was present to the first surrender of the Dutch New Amsterdam to the English. He was clerk of the court in the new English colony and served various judge roles.
He was a member of the Convention at Hempstead, New York in 1664-1665 that established the laws for the new colony.
In 1672 he was appointed New York City Mayor, and served for two years.
He was Speaker of the General Assembly under Thomas Dongan in 1684 which guaranteed religious freedom to Christians.
One of his children, William Nicoll, would sell the Plandome Manor in 1718, then over 1000 acres, and move to his own estate of 100 square miles (260 km2) on the Great South Bay in present day Islip, New York. The Suffolk estate Islip was named after their ancestral home in England.
He and his wife were buried in front of the manor home, although the exact spot is not now known because it was vandalized. A plaque on Plandome Road marks the general area.
