30 most inspiring women
"Role models mean different things to different people -- some of us look for guidance in business, some in our personal lives, some of us strive to make the world a better place each day, some admire trailblazers," Forbes said.
Roy comes in third on the list, while Nooyi ranks 10.
The '30 Utterly Inspiring Role Models' list has been compiled by ForbesWoman.
The publication reached out to communities on Facebook and Twitter to determine the most motivating women in the world.
Winfrey, who was named the 'Most Powerful Celebrity' by Forbes last month, leads the pack for the most inspirational role model.
"Ms. Winfrey's role model status extends beyond her professional career; her philanthropic work, including the Oprah Winfrey Leadership Academy for Girls, is just as inspiring," Forbes said.
