Pratek Man Tuladhar (Devanagari: प्रत्येक मान तुलाधर) (1924–1991) was a Nepalese trader and philatelist. Born in Kathmandu into a family of hereditary merchants, he spent his youth in Lhasa, Tibet, where they owned a business house. During his stay in Tibet (1939–1960), alongside his main occupation of conducting trade between India, Nepal and Tibet, he developed an avid interest in collecting photographs, postage stamps and coins.
