Thomas Osborne Davis (14 October 1814 – 16 September 1845) was an Irish writer; with Charles Gavan Duffy and John Blake Dillon, a founding editor of The Nation, the weekly organ of what came to be known as the Young Ireland movement. While embracing the common cause of a representative, national government for Ireland, Davis took issue with the nationalist leader Daniel O'Connell by arguing for the common ("mixed") education of Catholics and Protestants and by advocating for Irish as the national language.
