The double membrane that separates the nucleus from the cytoplasm is known as the nuclear envelope.

Explanation:

• The nuclear envelope, also called the nuclear membrane, consists of two lipid bilayer membranes: an inner membrane and an outer membrane.
• These membranes are separated by a space called the perinuclear space.
• The nuclear envelope serves to protect the genetic material within the nucleus and regulates the exchange of materials (such as RNA and proteins) between the nucleus and the cytoplasm through nuclear pores.

In summary, the nuclear envelope is the double membrane that separates the nucleus from the cytoplasm.
