Old Trafford is a cricket ground in Old Trafford, Greater Manchester, England. It opened in 1857 as the home of Manchester Cricket Club and has been the home of Lancashire County Cricket Club since 1864. From 2013 onwards it has been known as Emirates Old Trafford due to a sponsorship deal with the Emirates airline.

Old Trafford is England's second oldest Test venue after The Oval and hosted the first Ashes Test in England in 1884. The venue has hosted the Cricket World Cup five times (1975, 1979, 1983, 1999 and 2019). Old Trafford holds the record for both most World Cup matches hosted (17) and most semi-finals hosted (5). In 1956, the first 10-wicket haul in a single innings was achieved by England bowler Jim Laker who achieved bowling figures of 19 wickets for 90 runs—a bowling record which is unmatched in Test and first-class cricket. In 1990, a 17 year old Sachin Tendulkar scored 119 not out against England, which was the first of his 100 international centuries. In the 1993 Ashes Test at Old Trafford, leg-spinner Shane Warne bowled Mike Gatting with the "Ball of the Century".

After Old Trafford lost test status in 2009, extensive redevelopment of the ground to increase capacity and modernise facilities saw the restoration of the pavilion and creation of The Point, a £12 million stand overlooking the pitch.

The site was first used as a cricket ground in 1857, when the Manchester Cricket Club moved onto the meadows of the de Trafford estate. Despite the construction of a large pavilion (for the amateurs—the professionals used a shed at the opposite end of the ground), Old Trafford's first years were rocky: accessible only along a footpath from the railway station, the ground was situated out in the country, and games only attracted small crowds. It was not until the Roses match of 1875 that significant numbers attended a game. When W. G. Grace brought Gloucestershire in 1878, Old Trafford saw 28,000 spectators over three days, and this provoked improvements to access and facilities.

In 1884, Old Trafford became the second English ground, after The Oval, to stage Test cricket: with the first day being lost to rain, England drew with Australia. Expansion of the ground followed over the next decade, with the decision being taken to construct a new pavilion in 1894.

The ground was purchased outright from the de Traffords in 1898, for £24,372, as crowds increased, with over 50,000 spectators attending the 1899 Test match.

In 1902, the Australian Victor Trumper hit a hundred before lunch on the first day; Australia went on to win the Test by 3 runs—the third-closest Test result in history.

Crowds fell through the early 20th century, and the ground was closed during the First World War; however, in the conflict's aftermath, crowd numbers reached new heights. Investment followed throughout the inter-war period, and during this time, Lancashire experienced their most successful run to date, gaining four championship titles in five years.
