Tilly Lynde (October 9, 1782 – March 1, 1857) was an American merchant, judge, and politician in the U.S. state of New York.

By all reports, he was extremely successful in business and within a decade was a prominent and well-known member of the community.

Tilly's younger brother, Charles W. Lynde, also served in the New York State Senate.

Tilly Lynde married Eliza Warner, a school teacher from Sunderland, Massachusetts, on September 10, 1812.

Two of their sons, Charles and Watts, died along with 250 other passengers in the fire aboard the steamboat Erie, en route to Chicago in 1841.
