Dhunbai Cowasji Jehangir (1860 – 15 July 1940) was an Indian philanthropist and leader of women's organizations, based in Bombay.

[3] Jehangir was a co-founder and secretary of the Princess Mary Victoria Gymkhana, a women's social and educational club in Bombay.

[3] "There was hardly a movement intended to secure the educational and social progress of women with which the late Dowager Lady Cowasji Jehangir was not actively associated," noted one tribute in 1940.

[1] They had three children, all born before 1880, including two daughters, Cooverbai (who died as a young woman) and Bapsey Sabavala, and their son Sir Cowasji Jehangir, 2nd Baronet.

[10] The Sorabji Ratanji Patel Agiary in Pune includes a hall named for Lady Dhunbai Cowasjee Jehangir.
