#5 Nate Diaz – 2.1m followers
He might not have actually stepped into the Octagon since his August 2016 loss to Conor McGregor, but the shadow of Nate Diaz always seems to loom large over the UFC – and his large following on Instagram seems to prove that. After seeing his popularity soar thanks to his fights with McGregor, Diaz can now boast even more Instagram followers than his older brother Nick – who has 1.1m and narrowly missed out on this list.
Often a figure of controversy, it’s hardly a shock that the majority of Diaz’s snaps involve him posing and throwing up gangster hand signs, training Brazilian Jiu-Jitsu, or posing with his brother or teammates like Gilbert Melendez and Jake Shields. And it’s equally unsurprising that a post from November 2016 sees him openly smoking a joint – something that’s landed him in hot water on numerous occasions.
