Since 1998, Fortune has produced an annual list on The Most Powerful Women in Business. But what started 16 years ago as a ranking of the world’s top female leaders has transformed into a multimedia brand including live conferences, a daily newsletter and an online channel. As the franchise grows and expands, the Fortune Most Powerful Women team is constantly looking for inspiration and news from the world’s top female talent. Like many others, our go-to place for that info is often Twitter.

Here are 55 of our favorite women to follow on Twitter who actively champion gender diversity and leadership both professionally and on social media. (Editor’s note: The women are in no particular order.)
