The Product G&B is an American hip hop/R&B vocal duo consisting of David McRae (also known as Sincere Gubano) and Marvin Moore-Hough (also known as Money Harm).

Upon their debut in the late 1990s, the duo lent their vocals to several tracks on Pras' Ghetto Supastar (1998) album, such as the single "Blue Angels".

In 1999, Wyclef Jean convinced Arista Records chief Clive Davis to release the track "Maria Maria"—The Project G&B's collaboration with legendary musician Carlos Santana—as a late summer single, a decision which contributed to Santana's Supernatural (1999) album eventually selling over 30 million copies worldwide.

Later, in 2009, the duo was featured on Squala Orphan's song "U Don't Know" from the album Unheard Cries (2009).
