The Todd Seminary for Boys (1848–1954) was an independent preparatory school located in Woodstock, in the U.S. state of Illinois. From 1930 it was called the Todd School for Boys. Under headmaster Roger Hill from 1929, it became a progressive school that provided students including Orson Welles with a creative educational environment that emphasized practical experience over traditional academics. Only one building, Rogers Hall, remains from the original campus.
