Eclipse Park was the name of three successive baseball grounds in Louisville, Kentucky in the late 19th and early 20th centuries. They were the home of the Louisville baseball team first known as the Louisville Eclipse and later as the Louisville Colonels. The unusual name for these ballparks derived from the original name of the Association club, the Eclipse. The more local name "Colonels" eventually won out. Nonetheless, "Eclipse" was among the early team names to be a singular word, despite "sounding like" a plural.
