WonderSwan（日语：ワンダースワン，简称为WS）是日本玩具制造商万代（后与南梦宫合并为万代南梦宫）推出的16位掌上游戏机、第五世代游戏机，由Game Boy设计者横井军平成立的的公司Koto Laboratory和万代共同设计，并是横井军平在1997年因车祸逝世前主导设计的最后一款硬件。
初代WonderSwan于1999年3月于日本推出；派生机型包括于2000年推出的WonderSwan Color（日语：ワンダースワンカラー，简称为WSC），以及2002年推出的SwanCrystal（日语：スワンクリスタル，简称为SC）。在生命周期内，没有任何一款WonderSwan系列主机于日本以外的地区正式推出。
WonderSwan系列主机在其生命周期中销量共计约350万部，于日本掌上游戏机市场市占率最高达8%。尽管在市场龙头任天堂Game Boy系列的竞争下表现并不算突出，多数舆论仍给予WonderSwan正面评价。
