The Twin Zephyrs, also known as the Twin Cities Zephyrs, were a pair of streamlined passenger trains on the Chicago, Burlington and Quincy Railroad (CB&Q), running between Chicago and the Twin Cities of Minneapolis and Saint Paul in Minnesota. It was the second Zephyr service introduced by CB&Q after the record-setting Denver–Chicago "dawn to dusk dash" of the Pioneer Zephyr trainset.

The train competed with the Chicago and North Western's Twin Cities 400 which ceased operation in 1963, and the Milwaukee Road's Twin Cities Hiawatha, which, like the Zephyr, ended with the coming of Amtrak in 1971. The CB&Q trains went west from Chicago to the Mississippi River and along that river to Saint Paul, while the North Western and Milwaukee Road trains traveled via Milwaukee.
