Leo publicly rejected the label of feminist in statements made during a 2012 interview with Salon: "I don't think of myself as a feminist at all. As soon as we start labeling and categorizing ourselves and others, that's going to shut down the world. I would never say that." She reiterated these sentiments in a 2017 interview.

In 2010, Leo received fame for her role in David O. Russell's The Fighter. Rick Bentley of The Charlotte Observer said: "Both actors (Mark Wahlberg and Christian Bale) are very good, but they get blown off the screen by Melissa Leo, who plays their mother, Alice Ward. Leo's Oscar-worthy portrayal of Alice as a master manipulator goes beyond acting to a total transformation." Roger Ebert referred to it as a "teeth-gratingly brilliant performance." Leo and several of the film's actors including her co-star Amy Adams and Bale were nominated. For her performance Leo received several awards, including the Golden Globe, Dallas-Fort Worth Film Critics Association, New York Film Critics Circle, Screen Actors Guild, and culminating in her winning the Academy Award for Best Supporting Actress. While accepting her Oscar, Leo said: "When I watched Kate two years ago, it looked so fucking easy!" She apologized afterwards for using profanity, admitting that it was "a very inappropriate place to use that particular word ... those words, I apologize to anyone that they offend".
