Foundation is the fourth studio album by American hip hop group Brand Nubian.

The album marked the reunion of the four original members, Grand Puba, Sadat X, Lord Jamar and DJ Alamo, who hadn't released an album together since their 1990 debut One for All.

It features guest appearances from Busta Rhymes, Common and Loon.

Foundation saw the group regain their past success, critically and commercially.

Unlike previous releases, Foundation mostly features outside production, resulting in an updated sound.
