The Reid Professor of Criminal Law, Criminology and Penology is a professorship at Trinity College Dublin.
The chair is named after Richard Tuohill Reid (1823–83), an Irish lawyer and academic who was Perry Professor in Jurisprudence at Elphinstone College, a constituent college of the University of Bombay (now the University of Mumbai).
This was amended to its current name by the High Court on 3 March 1975.
While nominally a chair, appointments are made on the lecturer (assistant professor) scale.
The current holder is designated an adjunct assistant professor.
