Deshabandu Roshan Siriwardene Mahanama (Sinhala: රොෂාන් මහානාම, [roʃa:n maɦa:na:mə]; born 31 May 1966) is a former Sri Lankan cricketer and a former ICC match referee.

[2] In September 2015, Mahanama said that he would step down from the ICC match referee panel at the end of the year; he will spend his time with his family and his businesses.

He soon rose to prominence as a popular schoolboy cricketer with his unbeaten knock of 145 runs in the Annual Big Match against arch-rivals Ananda College.

[13][14][15] This record was surpassed in July 2006 as the largest partnership in Test match history by fellow Sri Lankans Kumar Sangakkara and Mahela Jayawardene who put on 624 against South Africa.

He captained the depleted Sri Lankan team at the 1994 Austral-Asia Cup which was held in Sharjah whereas main players such as Aravinda de Silva and Arjuna Ranatunga pulled out of the tournament for personal reasons.

These facts are mentioned in the book 'Retired hurt,' penned by noted Australian sports chronicler Ken Piesse, based on 40 hours of taped narration on Roshan's experience on and off the field.

[27] He joined the elite panel in 2004 and has refereed in 61 Tests, 222 ODIs and 35 T20Is till 15 September, including in three World Cups and the 2009 Champions Trophy.

He used to run pharmaceutical distribution business in Sri Lanka and also owns several startups including Zamon, an app which enables the consumers to order coffee and food from connected cafes.

[23] Former Australian cricketers Mark Taylor and Steve Waugh also ruled out the allegations calling Mahanama's claim as a publicity stunt.
