Sir James Key Caird, 1st Baronet (7 January 1837 – 9 March 1916) was a Scottish jute baron and mathematician. He was one of Dundee's most successful entrepreneurs, who used the latest technology in his Ashton and Craigie Mills.
Caird was noted for his interest in providing financial aid for scientific research. He was one of the sponsors of Sir Ernest Shackleton's ill-fated Antarctic expedition of 1914 to 1916. The ship's boat, the James Caird, in which six of Shackleton's expedition made an epic voyage of 700 nautical miles (1,300 km) from Elephant Island to South Georgia, was named in appreciation of Caird's contribution.
