Chai Kingdom is the fourth and final level of Super Mario Land, and a kingdom in Sarasa Land.

Chai is an oriental China type level, with a theme song that sounds Chinese. The first two levels are standard platformers, with several enemies but easy to access end-of-level minigames, and the third and final stage Mario flies in his Sky Pop. At the end, Mario must fight the cloud Biokinton, and finally Tatanga himself. In the final room is the real Princess Daisy.

Enemies found in Chai are Chibibos, Nokobons, Pakkun Flowers, Pompon Flowers, Pionpis, Giras, Nyololins, Chikakos, Chickens, and Roketons.
