The Magpies goalkeeper's close-range stop from Darwin Nunez in his side's New Year's Day defeat to Liverpool at Anfield is included, as is the Slovakian international's diving save to push Bernardo Silva's powerful effort onto the post in United's loss at home to Manchester City.
Everton custodian Jordan Pickford also has a couple of saves on the shortlist, while Aston Villa's Emi Martinez and Chelsea's Djordje Petrovic complete the list of nominees.
Dúbravka's teammate Anthony Gordon is also in the running for one of the top flight's monthly gongs - the Budweiser Goal of the Month award, for his effort against City.
