Onyx Coffee Lab is an American coffee roaster and coffee shop, based in Rogers, Arkansas. In February 2025 the roaster was named the "second best coffee shop in the world" by the website theworlds100bestcoffeeshops.com, and in 2026, Onyx Coffee Lab was awarded the title of "best coffee shop in the world", the first time an American cafe secured the top spot on the global ranking.
As of early 2026, the company operates eight retail cafes in Northwest Arkansas, with locations throughout Bentonville, Fayetteville, Rogers, and Springdale.
In 2022 Onyx announced a partnership with Jimmy Butler's coffee company BigFace, producing collaborative specialty coffee offerings.
