Charles Mears (March 16, 1814 – 1895) was a Michigan lumber businessman, capitalist, merchant, transportation executive, engineer, and farmer. He owned thousands of acres of timber in Michigan, and had 15 sawmills to produce lumber. Mears built cargo boats to transport his lumber to Chicago, and developed several harbors in western Michigan. A Republican, he was a friend of Abraham Lincoln. Mears had two of his settlements in Michigan renamed Lincoln and Hamlin to honor the successful 1860 Republican presidential ticket. Mears State Park in Pentwater is named after him.
