Square Grouper: The Godfathers of Ganja is a 2011 documentary by director Billy Corben (Cocaine Cowboys) and produced by Alfred Spellman and Billy Corben through their Miami-based media studio Rakontur. The term square grouper was a nickname given to bales of marijuana thrown overboard or out of airplanes in South Florida in the 1970s and 1980s.

In sharp contrast to the brazenly violent "Cocaine Cowboys" of the 1980s, Miami's marijuana smugglers were cooler, calmer, and typically nonviolent. Square Grouper paints a vivid portrait of Miami's pot smuggling culture in the 1970s and 1980s and its major players: the smuggling Black Tuna Gang, the pot dealing Ethiopian Zion Coptic Church and the tiny fishing village Everglades City.
