Mackenzie Lynne Dern (born 24 March 1993) is an American–Brazilian mixed martial artist celebrated for her elite Brazilian jiu-jitsu pedigree and evolution into one of the UFC’s most dangerous strawweights. A multiple-time world champion in jiu-jitsu before transitioning to MMA, Dern quickly built a reputation for her submission prowess, aggressive ground game, and relentless competitiveness. Competing at the highest level, she has consistently proven herself as a title contender, blending world-class grappling with steadily improving striking to remain a formidable force in women’s MMA.

Outside the Octagon, Mackenzie Dern’s style is confident, feminine, and effortlessly athletic, reflecting a balance between discipline and self-expression. She favours clean silhouettes, relaxed tailoring, and activewear-inspired looks that feel both practical and polished. Eyewear plays a subtle but defining role in her off-duty aesthetic, often adding refinement to her everyday style. Dern has been seen wearing fashion-forward frames from Cartier, gravitating towards squared metal-framed sunglasses and dark lenses that suit both travel and public appearances. Whether attending media events, training camps, or stepping out casually, her eyewear complements a look that is strong, modern, and self-assured — mirroring the confidence and resilience that define her career inside the cage.
