Sir Dominic John Corrigan, 1st Baronet (2 December 1802 – 1 February 1880), was an Irish physician, known for his original observations in heart disease.

He was attracted to the study of medicine by the physician in attendance, and spent several years as an apprentice to the local doctor, Edward Talbot O'Kelly.

Corrigan studied medicine in Dublin later transferring to Edinburgh Medical School where he received his degree as MD in August 1825.

Apart from his private practice, Corrigan held many public appointments; he was a physician to Maynooth College, the Sick Poor Institute, the Charitable Infirmary Jervis Street (1830–43) and the House of Industry Hospitals (1840–1866).

His work with many of Dublin's poorest inhabitants led to him specialising in diseases of the heart and lungs, and he lectured and published extensively on the subject.

He did not stand for re-election in 1874; his support for temperance and Sunday closing (of pubs) is thought to have antagonised his constituents and alcohol companies.
