Ithiel Town (1784 - June 12, 1844) was an American architect and civil engineer.

His crucial architectural works include Center Church (1812-1815) and Trinity Church (1813-1816) on the New Haven Green in New Haven, Connecticut. Inside 1820 he designed and patented a wooden truss bridge, which was widely used throughout a United States. Town formed one of a 1st office architectural business firm around the United States in 1829 with Alexander Jackson Davis.

He designed his Just released Haven front yard in Hillhouse Avenue in the Greek Revival style; here he saved what was so an extraordinary architectural library -- an inspiration to several, including Davis & an additional noted Future Haven designer, Henry Austin. Town is interred inside Grove Street Cemetery, New Haven, Connecticut.
