In human mitochondrial genetics, Haplogroup L4 is a human mitochondrial DNA (mtDNA) haplogroup.

It is a small African haplogroup.[2]



L4 is important in East Africa and Horn of Africa. The highest frequencies are in Tanzania among the Hadza at 60-83% and Sandawe at 48%.[3]



This phylogenetic tree of haplogroup L4 subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation[1] and subsequent published research.
