Adelheid von Rothschild (also Adélaïde de Rothschild, 19 August 1853 – 22 June 1935) was a member of the Rothschild family.

Adelheid was born on 19 August 1853 in Frankfurt. She was one of three daughters of Wilhelm Carl von Rothschild and Mathilde Hannah von Rothschild of the Naples branch of the Rothschild family.

Her paternal grandparents were Carl Mayer von Rothschild and Adelheid (née Hertz) von Rothschild. Her maternal grandparents were Anselm von Rothschild and Charlotte Nathan Rothschild (the daughter of Nathan Mayer Rothschild).

In 1877, she married her cousin Baron Edmond Benjamin James de Rothschild (1845–1934), the youngest child of James Mayer Rothschild and Betty von Rothschild. Together, they were the parents of three children:^[1]
