Triple centuries in Test cricket have been achieved on 23 occasions by 20 different batsmen from six of the ten Test-cricket playing nations. A triple century occurs when a batsman scores 300 runs or more in a single innings. No player from Bangladesh, New Zealand, South Africa or Zimbabwe has scored 300, although Martin Crowe of New Zealand was dismissed for 299 in a match against Sri Lanka in 1991.
The first, Test triple century was achieved by Andy Sandham of England against the West Indies in 1930 in the first Test series hosted in the West Indies. The most recent Test triple century (as of February 25, 2009) is that of Younus Khan of Pakistan against Sri Lanka in the first Test of their 2008–09 series in Karachi. The frequency of a batsman scoring a Test triple century is slightly less than that of a bowler taking a Test hat-trick (23 triple centuries versus 36 hat-tricks as of February 2009). The quickest Test triple-century was scored in 4 hours 48 minutes, by Wally Hammond for England against New Zealand at Auckland in 1932-33. The fastest Test triple-century by number of balls faced, where that figure is recorded, is Virender Sehwag's 278 ball triple century for India against South Africa in the first Test of the Future Cup in Chennai in 2008.
Brian Lara of the West Indies, Donald Bradman of Australia and Virender Sehwag of India are the only batsmen to reach 300 more than once. Bradman also scored 299 not out against South Africa in 1932. Lara's 400 not out against England in 2004, his second Test triple-century, is the highest score in Test cricket and the only instance of a Test quadruple century. Lara is also the only player to have surpassed 350 twice. Bradman also scored 299 not out against South Africa in 1932. Sehwag also reached 290 three times: he scored 293 off 254 balls in the third Test between Sri Lanka and India in December 2009.
The two cricket grounds with the most triple centuries scored at them are Headingley in Leeds, England, and the Antigua Recreation Ground in St. John's, Antigua and Barbuda, which have both had three triple centuries scored at them. The most triple centuries from one country is seven, by Australia.
