Axion theories, theories with a fundamental scalar having negative parity, arise naturally in a number of extensions of the Standard Model in particular in the Peccei-Quinn model that resolves the strong CP problem. In this talk I will discuss the Strong CP problem and its proposed resolution leading to the axion. I will then discuss the phenomenology of such an axion and the experimental searches this motivates as well as the possible role of the axion as dark matter. To date, no axion has been observed so I will discuss the current experimental bounds and ongoing searches.
