Sanjay Bhattacharya (b. 1958, Kolkata) is a celebrated Indian painter and photographer known for his deeply realistic depictions of urban life, particularly Kolkata's middle-class milieu. A graduate of the Government College of Arts and Crafts, Kolkata (1982), he began his career as an illustrator in advertising before turning full-time to painting. His early exhibitions, such as those at Dhoomimal Art Gallery (1988) and Jehangir Art Gallery (1992), brought critical acclaim. Bhattacharya’s works—especially in watercolour and oil—are noted for their photographic precision, mastery of light and shade, and emotional resonance. His deep engagement with the city of Kolkata is evident in his works, which offer an intimate portrayal of its homes, streets, and everyday lives. In 1994, his exhibition Rajiv Gandhi: Landscape of a Man was hosted by the National Gallery of Modern Art, marking a milestone in his career. He went on to paint official state portraits of Indian Presidents Dr. Shankar Dayal Sharma and K.R. Narayanan, which now reside in Rashtrapati Bhavan.

Influenced by masters like Rembrandt, Dalí, Bikash Bhattacharjee, and Ganesh Pyne, Bhattacharya eventually evolved a style that blends realism with personal narrative. He has received several awards, including honours from National Exhibitions (1981–85), AIFACS, and international recognition at the Ankara Biennale (1988). His works form part of several prestigious collections, notably those of the World Bank and the Parliament House in New Delhi.

 He currently divides his time between Delhi and Kolkata, continuing to explore themes that intertwine personal memory with the urban landscape.
