The Ultimate Fighter: Heavy Hitters (also known as The Ultimate Fighter 28) is an installment of the Ultimate Fighting Championship (UFC)-produced reality television series The Ultimate Fighter. The season tournament finale took place on November 30, 2018, at Pearl Theatre at Palms Casino Resort on Fox Sports 1.

Tryouts were announced on April 25, 2018. This season featured fighters from the women's featherweight and men's heavyweight divisions. The coaches for this season were announced on July 7, pitting The Ultimate Fighter: The Smashes winner and UFC Middleweight Champion Robert Whittaker against The Ultimate Fighter 17 winner Kelvin Gastelum. A middleweight title fight was scheduled between Whittaker and Gastelum after the show on February 9, 2019, at UFC 234. However, Whittaker pulled out of the event a few hours beforehand after he was forced to undergo emergency dual surgery due to an abdominal hernia of the intestine and a twisted and collapsed bowel. The pairing eventually met 2 years later at UFC on ESPN: Whittaker vs. Gastelum. The cast was announced on July 11, 2018.
