The accolade was given to the ITV series for "proudly showcas[ing] many talented Lgbt singers" during its 10-year run.
"The likes of Joe McElderry, Lucy Spraggan, Rylan Clark, Jaymi Hensley and, erm, Diva Fever have all been welcomed into viewers' hearts during The X Factor's 10-year run, and the show's contribution to Lgbt visibility shouldn't be underestimated," Attitude said.
"As well as new judge Nick Grimshaw, the current series has already thrown up a handful of varied Lgbt talent including the very unique Seann Miley Moore, who auditioned in a leather skirt and admitted, 'Music has allowed me to be me. If it makes you feel happy and right, then do it'. Amen!"
