NXT TakeOver: R Evolution was the third NXT TakeOver professional wrestling livestreaming event produced by WWE. It was held exclusively for wrestlers from the promotion's developmental territory, NXT. The event aired exclusively on the WWE Network and took place on December 11, 2014, at NXT's home arena, Full Sail University in Winter Park, Florida.

NXT is a brand of the American professional wrestling promotion WWE that was introduced on February 23, 2010. Brands are divisions of WWE's roster where wrestlers are assigned to perform on a weekly basis when a brand extension is in effect. Wrestlers assigned to NXT primarily appear on the brand's weekly television program, NXT. It serves as a developmental brand for Raw and SmackDown, which are WWE's primary brands considered as the main roster. Due to its developmental status, NXT operates regardless if there is a brand extension in effect or not.
