Among the television nominees were Bryan Cranston for "Breaking Bad," Claire Danes for "Homeland" and Kerry Washington for "Scandal."
The films are hallmarks of an extraordinary year for black cinema, rich with critical acclaim and box-office success, and Wednesday's nominations could signal more accolades to come -- and perhaps Academy Award recognition.
The SAG Awards, one of the leading Oscar bellwethers, honored "12 Years a Slave" with four nominations, more than any other film. The unflinching portrayal of slavery in early America earned a nod for best ensemble cast, the SAG Awards equivalent of best picture.
There were nominations as well for male actor in a leading role for Chiwetel Ejiofor and supporting nods for Michael Fassbender and Lupita Nyong'o.
"The Butler" earned three SAG nominations, including best ensemble cast, male actor in a leading role for Forest Whitaker and a supporting nod for Oprah Winfrey.
Rounding out the ensemble cast nominees were "August: Osage County" and "Dallas Buyers Club," which both earned three nods apiece, and "American Hustle," which also picked up a supporting nomination for Jennifer Lawrence.
Vying with Ejiofor and Whitaker for male actor in a leading role honors were Bruce Dern for "Nebraska," Tom Hanks for "Captain Phillips" and Matthew McConaughey for "Dallas Buyers Club."
Notably missing from the category: Robert Redford, for "All Is Lost." Just last week, Redford won the New York Film Critics Circle award for best actor.
Contending in the female actor in a leading role category are Cate Blanchett for "Blue Jasmine," Sandra Bullock for "Gravity," Judi Dench for "Philomena," Meryl Streep for "August: Osage County" and Emma Thompson for "Saving Mr. Banks."
In the supporting categories, Fassbender will be competing against Barkhad Abdi for "Captain Phillips," Daniel Bruhl for "Rush," the late James Gandolfini for "Enough Said" and Jared Leto for "Dallas Buyers Club." Nyong'o, Lawrence and Winfrey will vie against Julia Roberts for "August: Osage County" and June Squibb for "Nebraska."
On the TV side, the ensemble casts of "Boardwalk Empire," "Breaking Bad," "Homeland," "Downton Abbey" and "Game of Thrones" were nominated in the drama category. "Arrested Development," "Veep," "Big Bang Theory," "Modern Family" and "30 Rock" were honored with nominations in the comedy category.
Rita Moreno was previously announced as the winner of SAG's upcoming Life Achievement Award.
The SAG Awards will air live at 5 p.m. Jan. 18 on TBS and TNT.
