Samuel Smyth (c. 1929 – 10 March 1976) was a Northern Irish loyalist activist. A founder member of the Ulster Defence Association (UDA) he was the early public face of the movement as the organisation's spokesman, and he later became involved in the group's attempts to politicise. He was assassinated by the Provisional IRA as part of the Troubles. Author Steve Bruce described Smyth as the "sometime editor of the Ulster Militant and a loose cannon who enjoyed an exciting and erratic relationship with the UDA".[1]
