I will discuss cosmological aspects of the QCD axion and more general axion-like particles. I will then show how axions can play a key role in well-motivated baryogenesis frameworks, strengthening their motivation beyond the strong CP problem. Next, I will introduce a simple axion–monopole model in which the axion dynamics induces an effective interaction between dark matter and dark energy. I will close with recent developments in cosmological signals of axion dark matter and prospects for future detection.
