Sir John Salusbury Salusbury-Trelawny, 9th Baronet (2 June 1816 – 4 August 1885), was a British Liberal politician.
Born at Harewood on 2 June 1816 to Patience Christian Carpenter and Sir William Salusbury-Trelawny, the 8th Baronet of Trelawny.
In 1841 he was called to the bar, but never practiced and, in the same year, unsuccessfully contested Cornwall East Parliament Constituency as a Liberal.
He succeeded his father to the baronetcy in 1856 and retired from parliament in 1874 owing to "increasing infirmities".
