Vidyadhar Bhattacharya (Bengali: বিদ্যাধর ভট্টাচার্য) (1693-1751) was the chief architect and city planner of Jaipur, Rajasthan. A Bengali architect, who hailed from Naihati of present-day West Bengal, he was already working in the Amer state as Junior Auditor when approached by Maharaja Sawai Jai Singh II in 1727 to build one of the earliest planned cities of India. Along with Sir Samuel Swinton Jacob, he is credited as the architect of City Palace, Jaipur. He used principles of Shilpa Shastra and Vaastu Shastra to create a grid-based model of city.
The Vidyadhar Garden near Galtaji was built in memory of Purohit Vidyadhar Bhattacharya.
