Kaushalya Weeraratne (born January 29, 1981 in Gampola) is a Sri Lankancricketer. He is a left-handed batsman and a right-arm medium-fast bowler.
Though his batting is currently not as strong as his bowling (predominantly right-arm away-swingers), he is solid at both disciplines. He was part of the Sri Lankan under-19 World Cup squad in 2000 and was selected for that year's Asia Cup in Dhaka. Since 2005 he has played Twenty20 cricket.
Weeraratne had his secondary education at the prestigious Trinity College, Kandy, the only school in the world to own a Test class cricket stadium.
He holds the record for the fastest ever List A 50, beating Adam Hollioake's record by 3 runs in a 12 ball effort. His innings for Ragama included an over that went for 34 runs with 5 successive 6's.
