### Abstract

It is shown that the empirical eigenvalue distribution of suitably distributed random unitary matrices satisfies the large deviation principle as the matrix size goes to infinity. The primary term of the rate function is the logarithmic energy (or the minus sign of Voiculescu's free entropy). Examples of random unitaries are also discussed, one of them is related to the work of Gross and Witten in quantum physics.
