The Hankyu Imazu Line (阪急今津線, Hankyū Imazu-sen) is a 9.3 km long commuter rail line in Hyōgo Prefecture, Japan owned and operated by the private railway operator Hankyu Railway.

It is the longest of three branchlines of the Hankyu Kobe Line.

Typical Imazu Line trains stop every station between Imazu and Nishinomiya-Kitaguchi (south section) or Nishinomiya-Kitaguchi and Takarazuka (north section).

A small number of trains, called Semi-Express (junkyū), run from Takarazuka Station to Umeda Station (Hankyu's main terminal in Osaka) on weekdays not via the Takarazuka Line, but via the Imazu Line and the Kobe Line.

The section between Takarazuka and Nishinomiya-Kitaguchi opened on 2 September 1921, named the Nishi-Takarazuka Line (西宝塚線).
