Colin Blackburn, Baron Blackburn, PC (18 May 1813 – 8 January 1896) was a British lawyer and judge. The son of a Scottish clergyman, he was educated in Scotland and England, before joining the English bar. He was little known to the legal world before he was elevated from the junior bar to a puisne judgeship in the Court of Queen's Bench by Lord Campbell in 1859, a position he held until 1876, when he was appointed to the Court of Appeal. In October of that year, he was the first person to be appointed as a law lord under the provisions of the newly enacted Appellate Jurisdiction Act. He retired in 1886 and died ten years later.
