Baroness Doreen Lawrence will be named one of Cosmopolitan Magazine's Women of the Year this evening.
The campaigner, who entered the House of Lords last month, fought for 20 years to get justice for her son Stephen, who died in a racist attack in South London in 1993.
Along with her then husband, Baroness Lawrence helped uncover institutional racism within the Metropolitan police following the force's investigation into Stephen's death.
Cosmopolitan editor-in-chief Louise Court said Baroness Lawrence was "a true inspiration".
