Aishwarya Rajya Lakshmi Devi Shah (Nepali: ऐश्वर्य राज्य लक्ष्मी देवी शाह) (7 November 1949 – 1 June 2001) was the Queen of Nepal from 1972 to 2001, also referred to as Bada Maharani (बडामहारानी).

She was the eldest daughter of General Kendra Shumsher Jang Bahadur Rana (1921–1982) and his wife, Shree Rajya Lakshmi Shah (1926–2005).

Queen Aishwarya was shot dead along with her husband, King Birendra; her son, Prince Nirajan; her daughter, Princess Shruti; and seven other royal family members in the June 1, 2001 palace massacre.

It is widely believed that the motive for the murder was the strong opposition to the Crown Prince's proposed marriage to Devyani Rana.

Queen Aishwarya's face was so badly disfigured by the gunshot wound that, for the widely attended state funeral procession, it was covered by a porcelain mask bearing her likeness.
