Silas Webster Robbins (August 24, 1785 – June 19, 1871) was an American justice of the Supreme Court of Kentucky.
Immediately after graduation, he entered the Law School at Litchfield, under Judge Reeve, and in 1811 emigrated to Kentucky and began the practice of his profession in Winchester.
In the following year he was married, in Litchfield, to Caroline, youngest daughter of the late Uriah Tracy, at the time of his death (in 1807) U. S. Senator from Connecticut.
Having lost his wife in 1837, Judge Robbins removed in 1838 to Springfield, Illinois, where he resumed the practice of law.
In 1858, he retired from active life to his farm in the township of Springfield, about four miles from the city, where he died, 19 June 1871, aged nearly 86.
