Blain Supply, Inc., doing business as Blain's Farm & Fleet, is a regional, family-owned chain of 45 farm supply retail stores in four states (Wisconsin, Illinois, Iowa and Michigan) of the Upper Midwest region of the United States.

Blain's Farm & Fleet was an early adopter of "buy online, pick up at the store" in which all stores provide a drive-thru pick-up experience so online orders can be retrieved without consumers having to leave the car.

[2] Similarly-named Mills Fleet Farm was also founded in 1955 by Blain family friends.

In January 2018, the company announced it would be expanding into Michigan with 5 stores located in Portage, Jackson, Traverse City, Holland and Walker.
