Laurence F. Renehan (1797–1857) was an Irish historian, author, administrator and Roman Catholic priest who served as president of St Patrick's College, Maynooth from 1845 to 1857.
Renehan was born in 1797 at Longford Pass in the parish of Gurtnahoe, County Tipperary.
In September 1819, Renehan entered St Patrick's College as a student for the Archdiocese of Cashel to study logic.
On 15 September 1825, Renehan was appointed junior dean, and a few weeks later was ordained a priest.
