'''Protoia''' ([[greziera]]tik ''proton'' = lehena) oinarrizko [[partikula subatomiko]] nuklear bat da, oinarrizko unitate bateko (1.602 × 10−19 coulomb) karga elektrikoa duena. Hauek, [[atomo]] erdiguneko partikula bezala, partikula txikiagoez osatuak daude, eta partikula txiki hauei [[quark]] deritze.
 
Protoi batek hiru [[quark]] ditu, bi goiko quark eta behe quark bat.
