The field of axion physics has garnered significant attention in recent years. This is not only due to the absence of evidence for new heavy elementary particles, but also because the category of axion-like particles could elegantly account for several of our key observations, such as dark matter. In this presentation, I will provide an overview of the ongoing and forthcoming experimental endeavors aimed at detecting axions and, more broadly, axion-like particles, with a particular emphasis on searches conducted at the LHC. While we have not yet discovered any evidence of axion-like particles, these experiments may enable us to explore high-frequency gravitational waves, which will also be briefly discussed.
