In human genetics, Y-chromosomal Adam is the male counterpart to mitochondrial Eve: a real or hypothetical single male human ancestor from whom all male Y chromosomes are descended. Unlike other genes, those of the Y chromosome are passed exclusively from father to (only) sons, as mitochondrial DNA seems to be passed to (all) children by their mothers.

If such a person existed, he probably lived between 60,000 and 90,000 years ago, judging from molecular clock and genetic marker studies. While their descendants certainly became close intimates, Y-chromosomal Adam and mitochondrial Eve are separated by thousands of generations. They are named after "Adam" and "Eve" in Genesis, but by analogy and not literally.

Based on DNA analysis as of 2002, both Y-chromosomal Adam and mitochondrial Eve are believed to have lived in Africa; this is part of the Out-of-Africa theory of human evolution.

Human evolutionHuman evolution as a scientific field has a long and sometimes controversial history, however, since the mid- 1990s, there has been a remarkable convergence of views about how humans have evolved.
