Johann II (Johann Maria Franz Placidus; 5 October 1840 – 11 February 1929), nicknamed the Good (German: Der Gute), was Prince of Liechtenstein from 12 November 1858 until his death in 1929.
His reign of 70 years and 91 days is the third-longest of any sovereign monarch in European history, after those of King Louis XIV and Queen Elizabeth II respectively, and fourth-longest overall for which exact dates are known (after King Louis, Queen Elizabeth, and King Bhumibol Adulyadej respectively).
