Robert John Jackson (27 September 1948 – 30 May 1998), also known as The Jackal, was a Northern Irish loyalist paramilitary and part-time soldier. He was a senior officer in the Ulster Volunteer Force (UVF) during the period of violent ethno-nationalist conflict in Northern Ireland known as the Troubles. Jackson commanded the UVF's Mid-Ulster Brigade from 1975 to the early 1990s, when Billy Wright took over as leader.
