Lord Clifden (1860 – 7 February 1875) was a British Thoroughbred racehorse. He was undefeated as a two-year-old, including wins in the Woodcote Stakes and Champagne Stakes. As a three-year-old he was just beaten by a short-head in the Derby, before winning the St. Leger later in the season, despite being 100 yards behind the rest of the field at one point in the race. After an unsuccessful four-year-old campaign he was retired to stud and became champion sire of Great Britain and Ireland in 1876. He sired the St. Leger winners Hawthornden and Wenlock, the dual-Classic winners Petrarch and Jannette, as well as the champion sire Hampton. Lord Clifden was purchased by Carnegie Robert John Jervis, 3rd Viscount St Vincent, after his first race and was sold to Thomas Gee as a stallion. As the two and three-year-old he was trained by Edwin Parr, with William Bevill training him for his four-year-old season.
