Abstract: Over the last four decades, the axion has gone from being an elegant but undetectable dark matter candidate to becoming one of the primary targets of dedicated searches around the globe.  Many of these searches have been catalysts for the development of new technology to improve the sensitivity and effectiveness of detectors.  We discuss a few of the recent and upcoming experiments for axions and axion-like particles, with a particular focus on haloscopes, which use the axion-photon interaction to search for axion dark matter in the galactic halo.
