The list recognises companies that have benefits, policies and programs that are particularly beneficial for women to advance in the workplace.
FMG was the only Australian company out of the 34 to make the list.
Other companies to make the list included Adobe, Ralph Lauren and Pepsico.
Last year FMG was one of the first companies in Australia to sign Parity.org's ParityPledge to bring gender equality to the highest levels of business, making a public commitment to interview at least one qualified woman for every executive position.
FMG has a female CEO, Elizabeth Gaines, deputy CEO, Julie Shuttleworth, and four of its nine directors are female.
"Fortescue has long advocated the benefits of diversity and research continues to reinforce our view and experience that building a diverse workplace is not just the right thing to do, it's the smart thing to do," Gaines said.
"In fact, I believe our inclusive, diverse culture has strongly influenced Fortescue's industry leading performance, and has contributed to a 54% increase in our market capitalisation to A$42.6 billion over the 12 months to 30 June 2020."
FMG shares closed at a record $15.51 yesterday, capitalizing the company at $47.75 billion.
"Setting the tone for equality in the workplace starts from the top and I am proud that Fortescue continues to lead from the front with 44% female representation on our board of directors and a diverse management team with women representing 26% of our senior leadership," Gaines said.
"This is why we remain focused on building a pipeline of aspiring female leaders through a range of practical initiatives including paid parental leave, flexible working arrangements and leadership development programs."
Parity.org is a not-for-profit organisation dedicated to closing the gender gap at the highest ranks of business leadership.
"These companies are examples of commitment and intentionality in levelling the playing field for women and paving the way for them to succeed and advance their careers, making gender parity at the top levels possible," Parity.org founder and CEO Cathrin Stickney said.
