Rains Brook is a 11.8-kilometre-long (7.3 mi) tributary of the River Leam.
Formed by a series of small headwater streams midway between Barby and Kilsby in Northamptonshire, it then flows west in a valley south of Rugby on the border between Northamptonshire and Warwickshire. It then runs south-west to where it joins the River Leam, between Kites Hardwick and Woolscott.
