In human genetics, Haplogroup E-P147 is a human Y-chromosome DNA haplogroup. Haplogroup E-P147, along with the less common Haplogroup E-M75, is one of the two main branches of the older Haplogroup E-M96. The E-P147 clade is commonly observed throughout Africa and is divided into two subclades: the less common E-M33 & the more common E-P177.

Distribution
The Polymorphism P147 was first discovered in 2008 and contains the vast majority of men who belong to E-M96. The two branches of this lineage have different distributions, while the less common branch, E-M33, has more of a West African distribution, the more common branch, E-P177, can be found widely distributed with high frequency throughout Africa and to a lesser extent in the Middle East and Europe.
Phylogenetic history
Prior to 2002, there were in academic literature at least seven naming systems for the Y-Chromosome Phylogenetic tree. This led to considerable confusion. In 2002, the major research groups came together and formed the Y-Chromosome Consortium (YCC). They published a joint paper that created a single new tree that all agreed to use. Later, a group of citizen scientists with an interest in population genetics and genetic genealogy formed a working group to create an amateur tree aiming at being above all timely. The table below brings together all of these works at the point of the landmark 2002 YCC Tree. This allows a researcher reviewing older published literature to quickly move between nomenclatures.
Research publications
The following research teams per their publications were represented in the creation of the YCC tree.
