Caroline Bamberger Frank Fuld (nickname, "Carrie"; March 16, 1864 – July 18, 1944) was an American businesswoman and philanthropist.

The three of them were joined by a friend the Bamberger's had met in Baltimore, Felix Fuld, and all four would reside in a single-family home in South Orange, New Jersey, for the remainder of their respective lives.

In 1892, when running a business was considered a man's job, the three men as named partners, along with Carolyn who was or would be immediate family to all three, started the Newark, New Jersey–based department store that became L. Bamberger and Co. All four worked in the store and developed new methods of retail advertising and selling.

In 1913 she married her other business partner, Felix Fuld, surviving well beyond his death in 1929.

Most remembered, however, is the decision in 1929 by Fuld and her brother to seek the advice of Abraham Flexner, and subsequently to support, and endow financially, his vision for what became the Institute for Advanced Study in Princeton.
