John Symonds Udal (10 November 1848 in West Bromwich, Staffordshire, England – 13 March 1925 in London) was an English-born cricketer, antiquarian, author, lawyer and judge.

He was called to the bar at London's Inner Temple in November 1875, and went on to practice Law on the Western Circuit before becoming Attorney General of Fiji in September 1889.

While serving as Chief Justice of the Leeward Islands, Udal successfully sued James Townsland Allen, editor of the Montserrat Herald, for libel.

On 1 November 1910, Allen was sentenced to nine months' imprisonment after a jury found him guilty on two counts of "wickedly and maliciously contriv[ing] and intend[ing] to scandalise and vilify the said John Symonds Udal in his office of Chief Justice of the said Colony, and to cause it to be believed that the said John Symonds Udal was not a fit and proper person to administer justice in his said office."

In particular, the jury condemned Allen for these words: "We as laymen certainly disapprove of His Honour's conduct which to say the least of it was not only ungracious and undignified, but savoured very much of mean cowardice, calculated to bring the administration of justice into contempt.

[7] He played a match against "Surrey Club" in July 1873[7] which was evidently enough to persuade WG Grace to invite him on a tour to Australia, though he was unable to go.
