Gusztáv, 5th Prince Batthyány-Strattmann (8 December 1803 – 25 April 1883) was a Hungarian nobleman who bred horses in England where he was commonly known as Count Gustavus Batthyány.

The Batthyány family traces its roots as far back as the founding of Hungary by Árpád in the year 896, its ancestor being one of seven princes called Urs.

In 1851 he signed a letter together with his brother Count Kázmér Batthyány, Bertalan Szemere, and Prince Paul Esterházy to his old friends, the Duke of Wellington and Lord Melbourne, accusing Lajos Kossuth of high treason and terrorism.

[4] Batthyany had a heart condition that enforced the early retirement of his horse Galopin at the end of the 1875 season, as it was feared that the excitement of watching him race again could put the Prince's life at risk.

[6] His executors sold off his bloodstock at the Tattersalls July Sale at Newmarket, and a legal action was brought against them by his eldest son.
