The Alton line is a railway line in Hampshire and Surrey, England, operated by South Western Railway; it is a relatively long branch of the South West Main Line.

The branch leaves the main line at Pirbright Junction to the west of Brookwood station, Surrey, then turns to the south-west. The route crosses and recrosses the Surrey/Hampshire border, serving the towns of Aldershot and Farnham, before reaching its present-day terminus at Alton in East Hampshire. The line originally continued west to Winchester; the section between Alton and New Alresford is preserved as the heritage Watercress line.

The Alton line was electrified (750 V DC third rail) during the late inter-war years by Southern Railway. Steam trains connected to the Mid Hants Watercress Railway (by way of rolling stock supply or special excursion) operate on the line.
