It is called the Metro.
The Paris Métro is an electric underground railway system; the term metro is also used in other countries to define a rapid transport system, not necessarily underground.
The underground is called "le métro" (short for "métropolitain", which isn't used any more) in French. However, outside of Paris, you should clarify by saying "le métro de Paris", especially if you are in a city with a different subterranean train system (subway/metro/underground).
Good grief, no. Only the bit inside metropolitan Paris is underground.

The London Underground is the largest in Europe and the oldest in the world.
The Métro is the Paris urban railway system (Chemin de Fer Métropolitain), equivalent to the New York Subway or the London Underground, but much better than either. Most of its lines are just below the streets, but some are deep underground and some are elevated above the roadway.
