The Hankai Line (阪堺電車阪堺線, Hankai Densha Hankai-sen) is a tramway in the cities of Osaka and Sakai, Osaka Prefecture, Japan.

The line's name comes from Osaka (大阪) (the kanji character for saka is also pronounced han) and Sakai (堺) (whose kanji contributed the kai).

In 1915 the company merged with the Nankai Railway which runs north and south in Osaka.

As motorization developed as an alternative form of transportation along with the construction of subway lines underneath major routes, the trams lost their passengers, causing Osaka's once-extensive tram network to shrink, with only the Hankai and Uemachi tram lines remaining.

[numbering 1] All trams from Ebisucho go only as far as Abikomichi, while Uemachi Line trains go through from Tennoji-ekimae to Hamadera-ekimae.
