There are nearly 100 Parisian streets, squares, boulevards etc. named after mathematicians in our archive.
Mostly, of course, they are French but there are some others too. For example, there is a place on the Avenue Marceau about 300 metres from the Arc de Triomphe where streets named after Newton, Galileo and Euler all come together.
Perhaps the most surprising fact is that there is no Paris street named after Fourier.
(The street on which he was born in Auxerre is now called after him as you can see AT THIS LINK.)

The Mairie de Paris have a website giving the history of all Parisian street names and if you click on the M next to the street you can see these details.
You can see a map by clicking on the G next to the street name.
The French Wikipedia has entries on most streets also. You can see these by clicking on the W next to the street name.
