Chromosome 17 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 17 spans more than 84 million base pairs (the building material of DNA) and represents between 2.5 and 3% of the total DNA in cells.

Chromosome 17 contains the Homeobox B gene cluster.

The following are some of the gene count estimates of human chromosome 17. Because researchers use different approaches to genome annotation their predictions of the number of genes on each chromosome varies (for technical details, see gene prediction). The most conservative estimate, from CCDS, represents a lower bound on the total number of human protein-coding genes.

The following is a partial list of genes on human chromosome 17. For complete list, see the link in the infobox on the right.
