Warushavithana Upul Tharanga (born 2 February 1985), commonly known as Upul Tharanga, is a Sri Lankan cricketer. He is a left-handed opening batsman and wicketkeeper.

Upul Tharanga had his education at Dharmasoka College, Ambalangoda. He started his cricket career as a teenager at his school. Having played for Nondescripts since the age of 15, he played for Sri Lanka's under-15, under-17 and under-19 squads. He had a successful under-19 World Cup in 2004 with successful innings of 117 and 61 in successive games. He was sent by the Sri Lankan cricketing board to play league cricket for Loughton Cricket Club in Essex.

Tharanga's Sri Lankan call-up in July 2005 made for a mixed 2005, after his family home was washed away by the Asian tsunami. His equipment, which was also washed away, was replaced by Kumar Sangakkara. Tharanga graduated to the "A" team and in July he was selected for the full squad.

On the 2006 tour of England he really began to develop, particularly in the one-day game, scoring over 300 runs in Sri Lanka's 5-0 whitewash of the hosts. In addition, Tharanga is also well known for taking part in a record-breaking first wicket partnership with Sanath Jayasuriya in the final match of this series. He finished off with 109 off 102 balls, and played a pivotal role in completing the whitewash against England.
