Arthur Laban Bates (June 6, 1859 – August 26, 1934) was a Republican politician, lawyer, and businessman from the state of Pennsylvania.

Bates received his early education through tutors before graduating from Allegheny College in 1880.

His political career took off when he was elected to the United States House of Representatives as a Republican to the Fifty-seventh and to the five succeeding Congresses.

After leaving Congress in 1913, having declined to run for another term, Bates returned to law and publishing.

He was also involved in the banking sector and continued to serve his party as a delegate to the Republican National Convention in 1924.
