Popigajaus krateris (rus. кратер Попигай) – didelis (ketvirtas pagal dydį Žemėje) smūginis krateris Sibire. Prieš 35,7 ± 0,2 mln. metų (vėlyvasis eocenas) smarkus bolido smūgis sudarė 100 km skersmens kraterį. Krateris yra už 1½ valandos skrydžio nuo Chatangos. UNESCO jį paskelbė geoparku – ypatingu geologiniu paveldu.
