UFC on Fox: Jacaré vs. Brunson 2 (also known as UFC on Fox 27) was a mixed martial arts event produced by the Ultimate Fighting Championship held on January 27, 2018, at Spectrum Center in Charlotte, North Carolina, United States.

Background
The event marked the promotion's fourth visit to Charlotte, and first since UFC Fight Night: Florian vs. Gomi in March 2010.
