Cucurbita okeechobeensis, the Okeechobee gourd, is a species of gourd in the family Cucurbitaceae, native to Mexico and the United States. There are two subspecies; one is endemic to Florida, primarily in the region around Lake Okeechobee, the other to the State of Veracruz in eastern Mexico.[2][3] Once abundant,[2] it has state and federal listing as an endangered species.[4]

One of its peculiarities is the yellow corolla not so common in other Cucurbita species
