The Ōtō Line (鴨東線 Ōtō-sen) is a railway line in Kyoto that opened on October 5, 1989 as a branch of the Keihan Electric Railway. The Ōtō Line re-established a rail connection between the Keihan Main Line and the Eizan Electric Railway, which had been severed when the Kyoto City streetcars ceased running in 1978.
The double-track line runs below Kawabata Street, along the left (eastern) bank of the Kamo River.
