Tightwad is a village in Henry County, Missouri in the United States. As of the census of 2010 there were 69 people, 31 households, and 18 families residing in the village.
Located astride Missouri Route 7 Tightwad was an unincorporated location until 1984, even though a U.S. Post Office had existed there at the turn of the 20th century. The village's unusual name is said to stem from an episode in which a store owner cheated a customer (who was a postman) by charging him an extra fifty cents for a better watermelon. Some sources claim the transaction involved a rooster rather than a watermelon. Due to its proximity to Truman Reservoir, Tightwad saw some limited growth starting in the mid-1980s. As of 2010, the village's business district included a bank, café, tavern, and convenience store.
According to the United States Census Bureau, the village has a total area of 1.01 square miles.
