Evidenced by astrophysical and cosmological observation, dark matter comprises the dominant fraction of matter in the universe. However, its particle nature is as of yet unknown, representing arguably the most tantalizing hint for searches for new fundamental physics beyond the Standard Model. In this talk, I will review the status of searches for a particle dark matter known as the axion, which is theoretically well-motivated and largely experimentally unprobed, with emphasis on its unique cosmology and ongoing efforts towards its indirect detection. I will also briefly discuss new results from the Xenon1T experiment which report a 3.5 sigma detection of a solar axion.
