Jonathan Christian, SL, QC, PC (I) (17 February 1808 in Carrick-on-Suir, County Tipperary – 29 October 1887 in Dublin), was an Irish judge. He served as Solicitor-General for Ireland from 1856 to 1858. He was a judge of the Court of Common Pleas (Ireland) from 1858 to 1867 when he was appointed Lord Justice of Appeal in Chancery. On the creation of the new Irish Court of Appeal in 1878 he served briefly on that Court, but retired after a few months.
Christian was considered one of the best Irish lawyers of his time, but as a judge he regularly courted controversy. His bitter and sarcastic temper and open contempt for most of his colleagues led to frequent clashes both in Court and in the Press. Though he was rebuked for misconduct several times by the House of Commons, no serious thought seems to have been given to removing him from office.
