Nyong'o given Glamour magazine gong
Actresses Lupita Nyong'o and Laverne Cox, fashion designer Sarah Burton, UN Ambassador Samantha Power and Chelsea Clinton are among those being awarded Women of the Year awards by US Glamour magazine.
The awards are to be presented in a star-studded ceremony at Carnegie Hall.
Lupita won a supporting-actress Oscar for her performance in Twelve Years A Slave, capping her swift rise to the top rungs of Hollywood and the fashion world. She was also named a new face of Lancome and appeared on the cover of People magazine's Most Beautiful issue, and will be appearing in the new Star Wars movie.
Laverne, from Orange Is The New Black, was the first openly transgender person to be nominated for an Emmy Award. In a press release, Glamour called her "the face of one of the biggest equality stories of 2014".
Burton is best known for designing Kate Middleton's wedding gown. She became creative director of Alexander McQueen in 2010, following the designer's death, and has been credited, Glamour noted, with boosting the British fashion industry.
Power, the US ambassador to the United Nations, was cited for her work in diplomacy "during a year when the UN Security Council held more emergency sessions than it had in the entire 10 years prior."
Clinton was honoured for her work with the Bill, Hillary and Chelsea Clinton Foundation. Glamour also cited her work on a partnership between the Clinton Foundation and the Bill and Melinda Gates Foundation to encourage achievement among women and girls across the world.
