The trio were revealed to be among the nominees for football's most prestigious individual prize when the list was published by France Football magazine on Monday.
Lewandowski has scored 44 times in 40 competitive outings for Bayern in 2017, helping them win the Bundesliga title with 30 strikes during the 2016/17 campaign while also firing Poland to a place at next summer's FIFA World Cup.
Lewandowski's Bundesliga tally last season only placed him second in the race for the Torjägerkanone, however, as Aubameyang set a new Bundesliga record for a foreign-born player with 31 goals to help Dortmund secure third place and automatic qualification for this season's UEFA Champions League group stage.
Hummels impressed for Bayern in his first season back in Bavaria having rejoined the club from Borussia Dortmund in summer 2016. A pivotal figure in Bayern's title win, Hummels was also central to Germany winning the FIFA Confederations Cup last summer, and has helped Die Nationalmannschaft qualify for next summer's World Cup with a 100% record.
Watch: Lewandowski and Hummels have a new boss, Jupp Heynckes.
Former Wolfsburg forward and 2008/09 Bundesliga title winner Edin Dzeko, who now plays for Roma, was also included on the shortlist as was another former Wolfsburg man, Manchester City's Kevin De Bruyne.
Ex-Bayern midfielder Toni Kroos was also nominated, one of seven players selected from back-to-back European champions Real Madrid.
