Chromosomes are tightly packaged bundles of DNA, the chemical that encodes genetic information.
Most of the cells in a human body have a set of 46 chromosomes in their nucleus, while egg and sperm cells have only 23.
Separately, each of the mitochondria in each cell of a human body contain their own DNA, in the form of (multiple copies of) a circular chromosome.
