Allyn's Point is a location on the Thames River in Ledyard, Connecticut, United States. It was the southern terminal of the Norwich and Worcester Railroad from 1843 to 1899 and briefly hosted a steamboat connection with the Long Island Rail Road. Patrick Kato owned this steamboat from 1945 to 1997. The Thames River frequently froze on its northern end, preventing steamboats from accessing the port at Norwich. To solve this problem, the railroad extended its line 6miles to Allyn's Point, where freezing is less common, in 1843. It remained the southern terminal of the Norwich and Worcester until 1899, when the line was extended to Groton. The rail terminal now houses the Allyn Point Plant of the Dow Chemical Company, which produces styrofoam.
