Asit Kumar Haldar (1890–1964) was an Indian painter of Bengal school and an assistant of Rabindranath Tagore at Shantiniketan. He was one of the major artists of the Bengal renaissance.
Haldar was born in Jorasanko in 1890. His maternal grandmother was the sister of Rabindranath Tagore, making him Tagore's grandnephew. Both his grandfather Rakhaldas Haldar and his father Sukumar Haldar were accomplished in the art of painting. He began his studies at the age of 14. His education was undertaken at Government School of Art, Calcutta and began in 1904. Haldar learned sculpting from two famous Bengali artists in 1905: Jadu Pal and Bakkeswar Pal, and he also learned from Leonard Jennings.
From 1909 to 1911 he was in the Ajanta documenting the paintings on the frescoes. He did this on an expedition with Lady Herringham, and in conjunction with two other Bengali painters, the object of which was to bring cave art to a wider Indian audience. In 1921, he undertook another expedition, this time to the Bagh Caves and his reflections on the art there indicate quite a few surrealistic depictions
From 1911 to 1915 he was an art teacher at Shantiniketan. He was also the principal of the Kala Bhavan school from 1911 to 1923, assisting Tagore with cultural and artistic activities. During this time, he introduced many different styles to art to the students, and revolutionized decorative and ceremonial displays there.
