The Pakistan national cricket team toured Ceylon in March to April 1949 and played four matches including two internationals against the Ceylon national team. As Ceylon had not then achieved Test status, the internationals are classified as first-class matches. Both games were played at the Paikiasothy Saravanamuttu Stadium in Colombo and Pakistan won them both. They won the first by an innings and 192 runs; the second by 10 wickets. Pakistan were captained by Mohammed Saeed and Ceylon by Derrick de Saram.
