In human genetics, Haplogroup E-M33 is a human Y-chromosome DNA haplogroup. Haplogroup E-M33, along with haplogroup E-P177, is one of the two main branches of the older E-P147. The E-M33 clade is divided into several subclades.

E-M33 is found most often in West Africa, and today it is especially common in the region of Mali. One study has found haplogroup E-M33 Y-chromosomes in as much as 34% (15/44) of a sample of Malian men, including 2/44 E-M44 and 13/44 E-M33/M132(xE-M44). In particular, the Dogon people of Mali have been found to carry haplogroup E-M33 with a frequency as high as 45.5% (25/55), making it perhaps the most common Y-DNA haplogroup in this population, though haplogroup E-P1 appears to be almost equally frequent among the Dogon (24/55 = 43.6%). Another study has found haplogroup E-M33 in 15.6% (44/282) of a pool of seven samples of various ethnic groups in Guinea-Bissau. Haplogroup E-M33 also has been found in samples obtained from Moroccan Berbers, Sahrawis, Burkina Faso (including E-M33/M132(xE-M44) in 2/20 = 10% Fulbe and 2/37 = 5.4% Rimaibe), northern Cameroon (including E-M44 in 9/17 = 53% Fulbe and E-M33/M132(xE-M44) in 3/15 = 20% Tali), Senegal (7/139 = 5.0%), Ghana (1/29 = 3% Ga, 1/32 = 3% Fante), Sudan (including 5/32 = 15.6% Hausa and 3/26 = 11.5% Fulani), Egypt, Calabria (including both Italian and Albanian inhabitants of the region), 1 Italian (from 67 tested) from Trentino in northeastern Italy, and Romanians from Constanţa.
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.
|YCC 2002/2008 (Shorthand)||(α)||(β)||(γ)||(δ)||(ε)||(ζ)||(η)||YCC 2002 (Longhand)||YCC 2005 (Longhand)||YCC 2008 (Longhand)||YCC 2010r (Longhand)||ISOGG 2006||ISOGG 2007||ISOGG 2008||ISOGG 2009||ISOGG 2010||ISOGG 2011||ISOGG 2012|
The following research teams per their publications were represented in the creation of the YCC tree.
This phylogenetic tree of haplogroup subclades is based on the YCC 2008 tree and subsequent published research.
