British actress Tilda Swinton is also up for the award for her part in 'We Need To Talk About Kevin', alongside Viola Davis for 'The Help', Berenice Bejo for top-nominated film 'The Artist', and Williams for her role in 'My Week With Marilyn'.
Streep has already won a Golden Globe for her role in 'The Iron Lady', and is tipped for an Oscar.
Silent film 'The Artist' has scooped the largest number of nominations for the Orange British Academy Film Awards, with 12.
Cold War thriller 'Tinker Tailor Soldier Spy' follows with 11, including a leading actor nod for Gary Oldman.
His rivals at the awards, the biggest event in the British film calendar, include Brad Pitt for 'Moneyball' and George Clooney for 'The Descendants'.

The shortlist was announced at Bafta in Piccadilly by Harry Potter star Daniel Radcliffe, 'Great Expectations' actress Holliday Grainger and Bafta chairman Tim Corrie.
The five names competing for the top prize of best film are 'Tinker Tailor Soldier Spy', 'The Artist', 'The Help' - set in the racially-segregated American South of the early 1960s - comedy 'The Descendants' and crime thriller 'Drive'.
'Drive' star Carey Mulligan is up for supporting actress, competing with Dame Judi Dench for 'My Week With Marilyn'.

Scottish film-maker Lynne Ramsay is the British name up for best director, for 'We Need To Talk About Kevin', adapted from Lionel Shriver's best-selling novel about the mother of a boy who goes on a high-school killing-spree.
As well as Scorsese, 'The Artist' star Michel Hazanavicius, 'Drive' actor Nicolas Winding Refn, and 'Tinker Tailor Soldier Spy' star Tomas Alfredson are up for the award.
