Floyd Britton (April 21, 1937 in Colon – November 29, 1969 in Coiba Island) was a Panamanian leftist revolutionary and political leader.
A student leader from his days in secondary school, which he graduated in 1958, he participated in a failed guerrilla revolt the following year and then enrolled in the University of Panama.
With politics heavily influenced both by Castro's revolution and Maoism, he broke with the People's Party, forming one of two leftist sects.
At the commencement of the coup, Britton's political group merged with others to form the November 29 National Liberation Movement (MLN-29) which briefly engaged in armed struggle against the military regime.
Hundreds of political adversaries and civilians suffered the same fate as Britton during the regime's period in power, with the number being unknown.
