John Charles Bigham, 1st Viscount Mersey, PC (3 August 1840 – 3 September 1929) was a British jurist and politician. After early success as a lawyer and a less successful spell as a politician, he was appointed a judge and worked in commercial law.

After his retirement, Mersey remained active in public affairs and is probably best remembered for heading the official Board of Trade inquiries into the sinking of steamships, most notably RMS Titanic, RMS Lusitania, and RMS Empress of Ireland; and also Falaba, which gave rise to the Thrasher incident.
