George Ryoichi Ariyoshi is an American lawyer and politician who served as the third governor of Hawaii from 1974 to 1986. A Democrat, he is Hawaii's longest-serving governor and the first American of Asian descent to serve as governor of a U.S. state. He assumed gubernatorial powers and duties when Governor John A. Burns was declared incapacitated in October 1973 and was elected in 1974, becoming the first Asian-American to be elected governor of a U.S. state or territory. His lengthy tenure is a record likely to remain unbroken due to term limits enacted after he left office. Ariyoshi is now considered an elder statesman of the Democratic Party of Hawaiʻi.

The governor of Hawaii is the head of government of the U.S. state of Hawaii and its various agencies and departments, as provided in the Hawaii State Constitution Article V, Sections 1 through 6. It is a directly elected position, votes being cast by popular suffrage of residents of the state.
