Unfinished Business is the second album by hip-hop duo EPMD. Released July 25, 1989, the album built upon the success of the group's previous album Strictly Business, which was released the previous year. The lead single, "So Wat Cha Sayin'," was the only charting single released from the album. It was the second album from the group to hit No. 1 on the Top R&B/Hip-Hop Albums chart.

The album was certified Gold by the RIAA on October 16, 1989. It was one of three albums that Priority/EMI Records acquired from Sleeping Bag Records when it ceased operations in 1991; the other two were EPMD's debut, Strictly Business, and Nice & Smooth’s self-titled album. The rest of the Fresh/Sleeping Bag Records catalog was acquired by Warlock Records.
