The physical nature of the cosmic dark matter remains elusive, but several well-motivated extensions of the particle-physics standard model provide candidates that are experimentally searched. The axion, a hypothetical very low-mass boson motivated by quantum chromodynamics (QCD), will be introduced and its phenomenology, astrophysical limits, and ongoing experimental searches will be reviewed. The interest in low-mass bosons as dark matter, and axions in particular, has recently surged and a number of completely new search initiatives have emerged.
