String theory models generically predict the existence of multiple axion-like particle (ALP) fields, yet the majority of both theoretical and experimental works assumed only one ALP. In this paper, we discuss the phenomenology of systems multiple ALPs that can undergo oscillations akin to neutrino oscillations. Motivated by effect, we extend the 'anarchy' framework, which has been used to predict neutrino oscillation parameters, to generate the parameters of many ALP systems. We explore the phenomenology of these ALP anarchy models in some of the leading ALP search strategies, including CERN Axion Solar Telescope, magnetic white dwarfs and the gamma-ray spectra of distant blazars. We include both the ALP-photon and the ALP-electron coupling. We find that anarchy models predict drastically different results than single ALP models.
