The Cucurbitaceae, also called cucurbits and the gourd family, are a plant family consisting of around a hundred genera, the most important of which are:

• Cucurbita – squash, pumpkin, zucchini, some gourds
• Lagenaria – mostly inedible gourds
• Citrullus – watermelon (C. lanatus, C. colocynthis) and others
• Cucumis – cucumber (C. sativus), various melons
• Luffa – the common name is also luffa, sometimes spelled loofah (when fully ripened, two species of this fibrous fruit are the source of the loofah scrubbing sponge)
