Wonderful Hearts (ワンダフルハーツ) is a Hello! Project concert group. Since 2006, Hello! Project had been split into Wonderful Hearts and the Elder Club, but Wonderful Hearts was the only remaining unit upon the graduation of Elder Club on March 31, 2009.

Hello! Pro Kenshuusei usually appear with Wonderful Hearts as backup dancers.

As of January 2010, Wonderful Hearts has been disband as a concert unit due to the creation of Hello! Project Mobekimasu.
