Francis Blackburne PC (Ire) KS was an Irish judge and eventually became Lord Chancellor of Ireland.

The Master of the Rolls in Ireland was a senior judicial office in the Irish Chancery under English and British rule, and was equivalent to the Master of the Rolls in the English Chancery. Originally called the Keeper of the Rolls, he was responsible for the safekeeping of the Chancery records such as close rolls and patent rolls. The office was created by letters patent in 1333, the first holder of the office being Edmund de Grimsby. As the Irish bureaucracy expanded, the duties of the Master of the Rolls came to be performed by subordinates and the position became a sinecure which was awarded to political allies of the Dublin Castle administration. In the nineteenth century, it became a senior judicial appointment, ranking second within the Court of Chancery behind the Lord Chancellor of Ireland. The post was abolished by the Courts of Justice Act 1924, passed by the Irish Free State established in 1922.
