#2. Amanda Nunes - UFC women’s featherweight champion

Amanda Nunes lost the UFC women’s bantamweight title in her most recent fight but has held the featherweight belt since December 2018. The shocking loss to Juliana Peña is the reason Nunes does not top this list as she had held that title since July 2016.
‘The Lioness’ first won the featherweight belt when she shockingly knocked out Cris Cyborg inside a minute. Her only other two title fights in the division have come against Felicia Spencer and Megan Anderson. Nunes defeated Spencer via unanimous decision before submitting Anderson inside one round.

Nunes is guaranteed to hold onto the featherweight title for a little while longer as her next fight will be at 135 lbs in a rematch against Peña. It’s hard to predict her next title defense at 145 lbs given there are so few fighters on the roster in that division. Perhaps Peña could move up to face ‘The Lioness’ at 145 lbs one day.
#1. Valentina Shevchenko - UFC women’s flyweight champion

There may not be another division in the UFC with such a big talent gap between the champion and the rest of the contenders than women's flyweight. It should therefore be no surprise that Valentina Shevchenko is also the longest reigning champion in the company.
Shevchenko won the title from Joanna Jedrzejczyk in December 2018 and has successfully defended the belt on six occasions. She's knocked out the likes of Katlyn Chookagain and Jessica Andrade, and has even earned decision victories over Liz Carmouche and Jennifer Maia on this run.
Next to challenge for the belt will be Taila Santos on June 11. While you never know in the sport of MMA, Shevchenko will likely be a heavy favorite in that fight and most will expect her reign to continue. Who knows how long she will be able to keep this up?
