Chromosome 2 is one of the twenty-three pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 2 is the second-largest human chromosome, spanning more than 242 million base pairs[4] and representing almost eight percent of the total DNA in human cells.

Chromosome 2 contains the HOXD homeobox gene cluster.[5]
