Six incorporated cities and towns in the United States bear the name Ithaca—each inspired by the Greek island home of Odysseus, reflecting classical education's influence on 19th-century American settlers.
The name surged in popularity during the Greek Revival era (1820s–1850s) when American towns adopted classical names to signal culture and permanence. Homer's Odyssey was standard curriculum, making Ithaca a symbol of homecoming and endurance—appealing aspirations for frontier communities.
Only Ithaca, NY and Ithaca, MI are county seats. Ithaca, NY dominates culturally (the "Ithaca is Gorges" slogan, Moosewood Restaurant, Carl Sagan's tenure). The others remain small, rural, and largely unknown outside their regions.
