Neketh Gedara Roshan Prabath Jayasuriya, commonly known as Prabath Jayasuriya (প্রভাত জয়াসুরিয়া), is a professional Sri Lankan cricketer who plays for the national team in Tests and ODIs. In domestic matches, he plays for Colts Cricket Club and Jaffna Stallions. He bowls left arm orthodox spin and a lower order batsman who can bat a bit.

Jayasuriya is quickest Sri Lankan bowler to reach both 50 and 100 Test wickets in Sri Lanka.

Jayasuriya is a past pupil of Christ Church College, Matale and Lumbini College, Colombo.

He went onto represent Christ Church College U-13 and U-15 teams as well as Matale District XI U-15 team at the 2006 SLC Inter District Tournament. He was later chosen by the Matale Cricket Club to play in the 2007 Sara Division 1 Tournament.

He made his List A debut on 6 December 2011 for Colombo Cricket Club against Sri Lanka Army during the 2011/12 Premier Limited Over Tournament. He made his first-class debut playing for Colombo Cricket Club against Kurunegala Youth Cricket Club on 10 February 2012 during the 2011/12 Premier League Tournament Tier B. He made his T20 debut playing for Colombo Cricket Club against the Lankan Cricket Club on 26 March 2012 during the 2011/12 CSN Premier Clubs T20 Tournament.

In July 2018, he was named in Sri Lanka's One Day International (ODI) squad for their series against South Africa. He made his ODI debut for Sri Lanka against South Africa on 1 August 2018.

He was on the verge of making his test debut during the home test series against Bangladesh way back in April 2021 as an injury replacement to Lasith Embuldeniya but he was not included in the squad for failing skinfold fitness tests and Praveen Jayawickrama who had just 10 first-class games experience under his belt got the nod over the experienced premiere spinner at domestic level. The reason for his exclusion was initially reported by media that Jayasiriya had failed to complete the mandatory two kilometre fitness run inside eight minutes which was in force during the tenure of Mickey Arthur as head coach but the reports were rubbished by SLC as it clarified that Jayasuriya was snubbed based on his skinfold tests. Following Jayawickrama's incredible start to test cricket with twin fifers on debut against Bangladesh, the hopes of Jayasuriya making a case for himself at test level started to wane and Jayasuriya fell under the radar. Despite being a consistent performer at first-class level, Jayasuriya was made to wait for too longer.

He was awarded the ICC Men's Player of the Month Award for July 2022.
