The Academy of Motion Picture Arts and Sciences said the 27-year-old will join the organisation’s president Tom Sherak to reveal 10 of the 24 awards.
The nominations will be announced at the academy’s Beverly Hills headquarters on 2 February.
Hathaway was nominated for an Oscar in 2009 for her leading role in Rachel Getting Married.
However, the star lost out in the best actress category to Kate Winslet, who won the award for The Reader.
Hathaway’s other movie credits include The Devil Wears Prada and The Princess Diaries.
This year, the best picture category has been opened up to include 10 movies, instead of five.
The ceremony, on Sunday 7 March, takes place a fortnight later than last year’s event, to avoid coinciding with the Winter Olympic Games in Vancouver.
