This morning Google announced they have expanded where Google Map Maker is supported by adding an additional 8 countries bring the total to 190 countries.
Google Map Maker allows users, like you and me, to make edits to Google Maps to help make Google Maps more accurate and useful to everyone else. Yesterday, I wrote on Search Engine Land how one man made over 400 edits in a single month.
You can see the supported countries over here, currently all 190 of them. If your favorite country is not yet supported and want to be notified when it is, go to this URL to be notified.
