Pumpkin, but the word is often used for courgette, kolokytháki.
Pumpkin is not the most popular veg in Greece, where you're more likely to see the seeds as passatempo. Some people like to make them into glykó tou koutalioú.
If someone is talking nonsense, instead of saying ‘Baloney! ‘a Greek says ‘kolokýthia!’
