"OK" is the second single by British R&B collective Big Brovaz. It was also the second single taken from their debut album Nu-Flow, released in late 2002. The album was re-released two weeks after the release of "OK" with the "OK" radio edit added and bonus tracks.

"OK" became Big Brovaz' second UK top-ten hit, peaking at number seven and spending nine weeks inside the top seventy-five of the UK Singles Chart. Despite "Nu Flow" being a hit in Australia, "OK" was a commercial failure and their smallest hit there, peaking at a lowly number sixty-four.
