Yes, the window.beforeunload event.

The beforeunload event is fired when the window, the document and its resources are about to be unloaded. The document is still visible and the event is still cancelable at this point. - MDN Definition

Keep in mind that as user JoshG commented, it will also fire on things such as page close.
