The talk show legend was heavily tipped to earn an Academy Award nod for her return to acting in Lee Daniels' The Butler, however, she failed to make the cut when the nominations were announced on Thursday.
Oprah says she isn't at all upset about being snubbed and praised the women who were nominated in the Best Supporting Actress category, including Julia Roberts, Lupita Nyong'o, Jennifer Lawrence, June Squibb and Sally Hawkins.
She said: "I do not think I was robbed at all. How dare anybody say that I was robbed ... Robbed? Are you kidding? Never, never, never!
"Because when you look at the category - Julia, and Sally, and June, and Jennifer, and Lupita!"
Oprah has earned a BAFTA nomination for her portrayal of Gloria Gaines - the wife of Cecil Gaines (Forest Whitaker), a butler who served no less than seven United States presidents - in the acclaimed historical film and she concedes it's difficult for Oscar voters to consider all of the films which vie for the coveted awards.
She told Access Hollywood: "That's what's so wonderful about the Oscars. There are wonderful films, and the fact that you have so many films that you can't even get people in all the categories. And the fact that I, actually, after 15 years was able to actually do it."
