Arthur Melvin "Art" Okun (November 28, 1928 – March 23, 1980) was an American economist.

Okun is known in particular for Okun's law, an observed relationship that states that for every 1% increase in the unemployment rate, a country's GDP will be roughly an additional 2.5% lower than its potential GDP. He is also known as the creator of the misery index, the analogy of the deadweight loss of taxation with a leaky bucket, and for the conception of "the invisible handshake".
