Pushpa Sundar Tuladhar (Nepali: पुष्पसुन्दर तुलाधर; 1885-1935) was a prominent merchant of Kathmandu and one of the chief donors to the restoration of the Swayambhu stupa in 1918. Swayambhu, a UNESCO World Heritage Site, is one of the holiest Buddhist shrines in Nepal and the center of Newar Buddhism. The renovation project was headed by his father-in-law Dharma Man Tuladhar and completed in 1921.
