Sam(uel) Thompson (21 May 1916 – 15 February 1965) was an Irish playwright best known for his controversial plays "Over the Bridge", which exposes sectarianism, and "Cemented with Love", which focuses on political corruption. His works fall into the social realist genre but are distinct in their dramatisation of Northern Irish issues; they were ground-breaking in documenting sectarian violence before the eruption of the Troubles.
