Mahaska (archaic Ioway Maxúshga pronounced [mõxuʃꜜkɐ]; contemporary Maxúhga), or White Cloud, (c. 1784–1834) was a chief of the Native American Iowa tribe.

Mahaska lay down his arms and adopted the lifestyle of the European-American settlers, building a log home and farming.

He refused to let his braves avenge the death of an Iowa chief named Crane at the hands of Omaha Indians in 1833.

The next year one of the Iowa escaped from Fort Leavenworth and killed Mahaska by shooting him in the back as he sat by his campfire.

Recently restored, it still stands on its pedestal in the courthouse square of Oskaloosa, which is the governmental seat of Mahaska County, Iowa, in the southeastern section of the state.
