International cricket in 2018

The 2018 international cricket season was from May 2018 to September 2018. 16 Test matches, 27 One-day Internationals (ODIs) and 33 Twenty20 International (T20Is), as well as 14 Women's One Day Internationals (WODIs) and 81 Women's Twenty20 Internationals (WT20Is), were played during this period.

The season started with India leading the Test cricket rankings, England leading the ODI rankings, Pakistan leading the Twenty20 rankings, and Australia women leading the women's rankings. This season was also the first to be scheduled under the 2018–2023 Future Tours Programme. In addition, all women's Twenty20 matches played between member sides after 1 July were given full international status and classified as WT20Is, as per a decision made by the International Cricket Council (ICC) in April 2018. The first WT20Is to be classified as such under these new rules took place at the 2018 ICC Women's World Twenty20 Qualifier.

This season also included Afghanistan's first Test match and Nepal's first ODI matches. Scotland beat England for the first time in ODIs after winning the one-off ODI in Edinburgh. Scotland's innings total of 371/5 was the highest score by an Associate team against a Full Member team. In the 3rd ODI of Australia's tour of England, England scored a new record high ODI innings total of 481/6 off 50 overs.
