Harsha de Silva (Sinhala: හර්ෂ ද සිල්වා born 30 August 1964) is a Sri Lankan economist and politician.

[5][6][7] He was the main backer of the Indian-aided project to create a modern EMT and Ambulance service in Sri Lanka.

When India offered a gift to Sri Lanka in order to mark Prime Minister Ranil Wickremesinghe's visit, De Silva proposed an emergency medical service after personal experiences with shortcomings in the Sri Lankan system as well the urging of doctors.

Wickremesinghe also backed it, leading India's GVK Emergency Response Institute to offer training to hundreds of Sri Lankan EMTs and Paramedics as well as donating ambulances and granting 7.5 million dollars to start the service in Colombo and Galle.

He became known as a media personality who hosted talk shows relating to development and international matters.
