Yakuman DS is a 2005 mahjong video game developed by Nintendo and MediaKite and published by Nintendo for the Nintendo DS. It is a successor to Nintendo's 1989 Game Boy game Yakuman. It features modern Japanese Mahjong rules (with riichi and dora) and various characters from the Mario video game series.

The original version was released in Japan in March 2005 by Nintendo. In September of the following year they re-released the game with an online mode and the revised title Yakuman DS with Wi-Fi Support. Both versions were released only in Japan and with predominantly Japanese text.

In Japanese Mahjong, the term yakuman can refer both to the rare high-scoring limit hands and to the largest score limit that can be applied to a winning hand under Japanese Mahjong scoring rules.

The game sold poorly, with both versions selling a combined total of less than 40,000 copies.^{[better source needed]}
