Which airport is closest to central Paris?

Of the two major Parisian metropolitan area airports, Orly is the closest to central Paris by way of distance.  However, since there is no express train that connects Orly to downtown Paris, it can take well over 30 minutes even in the best traffic conditions. Orly primarily offers regional and budget flights.  So, the chances are high that your incoming international flight will be at Charles de Gaulle Airport.  Though further away from central Paris by distance, Charles de Gaulle Airport is connected by express trains that can take one to the core of the city within 35 minutes.
