As of September 2011, there are no Yoshi games that were made for the Nintendo 3DS. However, Yoshi will be appearing in a few Mario 3DS games coming up, like Mario Kart 7. Also, Nintendo 3DS ambassadors can download the NES game "Yoshi" from the Nintendo eShop for free, and the rest of the world will be able to before the end of 2011.
