Karuna Ratna Tuladhar (Nepali: करुणारत्न तुलाधर) (23 October 1920 – 19 July 2008) was a pioneer of Nepalese public transport. He was proprietor of Nepal Transport Service which he and his brother Lupau Ratna Tuladhar founded in 1959. This was Nepal's first public bus service which linked the capital Kathmandu with the railhead of Amlekhganj, 190 kilometers to the south near the Indian border. The same year, Nepal Transport Service also started the first local shuttle between Kathmandu and Patan (Lalitpur), one of the three cities in the Kathmandu Valley.
