Jonathan Osborne MD FRCPI (died 22 Jan 1864) was an eminent Irish physician and surgeon.
In 1823 he was elected Fellow of the College of Physicians and in 1825 lecturer of Materia Medica in Park St. Medical School.
These indicate that he visited counties Clare and Galway including the Aran Islands, as well as Mayo before 1833.
With his wife Catherine, he had a son, Verney, and daughter Florence (who married Rev.
William H. Rambaut), both of whom died as young adults and are interred with him in St. Michan's Church, Dublin.
