Alphonso Wood (1810 – January 4, 1881) was an American botanist and theology instructor.
Wood studied at both Dartmouth College and Andover Theological Seminary.
He started his teaching career as the Latin and natural science instructor at Kimball Union Academy in Meriden, New Hampshire.
He retired from his instructional work in 1867 and lived the remainder of his life in West Farms, New York.
[1] In an obituary in The Gardener's Monthly and Horticulturist, Wood was described as performing the important task of taking the progressive scientific research of botanists and making their "knowledge widely distributed" through "universal" textbooks.
