Olaf Anders Tveitmoe (December 7, 1865 - March 19, 1923) was a Norwegian-born American teacher, newspaper editor, and labor leader.

He is best remembered for tangential trade union activity as the founder and president from 1904 to 1912 of the Asiatic Exclusion League, a political organization which sought to bolster American domestic wage levels by restricting immigration from Japan, China, and Korea.

[1] Later, Tveitmoe moved to the Pacific Coast, settling first in the state of Oregon, where he was instrumental in organizing a utopian socialist communal colony.

[4] Despite his new role as a trade union functionary, Tveitmoe remained involved in journalism as editor of the weekly newspaper Organized Labor from 1900 until 1920.

[6] Despite being considered a loyalist, however, Tveitmoe immediately refused to attend Abe Ruef's "caucus meetings," rumored to be where the Union Labor boss directed his men on how to vote.

[9] This was followed on May 7, 1905 with a mass meeting at Metropolitan Hall in San Francisco chaired by Tveitmoe, at which was established the Japanese and Korean Exclusion League.
