Arthur Yager (October 29, 1858 – December 24, 1941) served as the governor of Puerto Rico from 1913 to 1921.

He earned bachelor's and master's degrees from Georgetown College in Kentucky, and a doctorate from Johns Hopkins University.

During Yager's administration, and with his support, the United States Congress adopted the Jones-Shafroth Act (also called Jones Act) of 1917, which imposed United States citizenship on Puerto Ricans.

He was succeeded by Emmet Montgomery Reily, an appointee of President Warren G. Harding.

A collection of Yager's correspondence from his time as Governor is archived at the Filson Historical Society in Louisville, Kentucky and open for research.
