Obert A. Olson (April 23, 1882 – August 22, 1938) was a North Dakota public servant and politician with the Republican Party (Nonpartisan League faction).

He set up a farm and cattle operation and also started a real estate business in Bowman.

During the 1919 regular session of the state legislature, he spoke out against the newspaper and Board of Administration bills that were supported by the NPL.

Olson became president of the Farmers' Insurance Company, which had its home office in Dickinson.

"[8] In October 1919, between the regular and special legislative sessions, there was talk of impeaching Olson for speaking out against the NPL.

Olson was grouped in with the other "troublemakers," William Langer, Thomas Hall, and Carl Kositzky, who had openly defected from the NPL.

However, in a surprise move, or perhaps to make amends, the NPL endorsed Olson for state treasurer again in 1922.

[3][2] Olson was buried at Saint Mary's Cemetery in Burleigh County, North Dakota.
