Lorrin Alanson Cooke (April 6, 1831 – August 12, 1902) was an American politician and the 57th governor of Connecticut from 1897 to 1899.

He joined the local agricultural society, was elected president, and his leadership began to develop.

Cooke worked with railroad officials to route a train through the remote Colebrook area, increasing sales as produce was freighted to the big city, and the town prospered.

His election to the Connecticut General Assembly as the representative from the town of Colebrook in 1856, when he was only 25 years old, gave him his first experiences in state politics.

During his term, he was successful in his attempts in leaving a financially sound state treasury, even with increased governmental expenditures, which resulted from the outbreak of the Spanish–American War.
