Lewis Wolfley (October 8, 1839February 12, 1910) was an American civil engineer who served as the eighth Governor of Arizona Territory. He is commonly regarded as the first territorial governor to be a resident of Arizona at the time of his appointment and was the only bachelor to hold the position. Wolfley's political career was marred by his almost complete lack of political skill. Much of his time as governor was spent in political infighting, which eventually led to his resignation.
