History
The town was part of the former Central New York Military Tract. The town was first settled by outsiders around 1798, but permanent settlement began around 1801. The Town of Otisco was formed in 1806 from parts of other towns: Pompey, Marcellus, and Tully.

The name "Otisco" may have been derived from the Iroquois name for Nine Mile Creek, Us-te-ke, meaning "bitter-nut-hickory". At least one older map, published in 1825, has the name spelled as "Ostisco". The name may also have been derived from the word ostickney, meaning "waters much dried away", or from the Onondaga word ostick, meaning "the water is low".
