James Dennistoun of Dennistoun (1803–13 February 1855) was a Scottish advocate, antiquary and art collector.Dennistoun was born in Dumbartonshire in 1803, the eldest son of Mary Ramsay, daughter of George Oswald of Auchencruive and James Dennistoun (died 1 June 1834). After receiving his education at the universities of Edinburgh and Glasgow, he became a member of the Faculty of Advocates in 1824. During a continental tour in 1825 and 1826, in which his companions were Mark Napier, Hamilton Gray, and Sir Charles Fergusson, the art and literature of Italy first engaged Dennistoun's attention. After his father's death he sold the family estate on the shores of the River Clyde and purchased the farm of Dennistoun in Renfrewshire, the centre of the original possessions of his family in that county.
