Alphonso Wood (1810 – January 4, 1881) was an American botanist and theology instructor. He was the author of several works on botany that were popularly used as instructional texts in the 19th century.
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.[2]
