The Keihan Ishiyama Sakamoto Line (京阪石山坂本線, Keihan Ishiyama Sakamoto-sen^?) is a railway line in Shiga Prefecture, Japan, operated by the Keihan Electric Railway.

The Otsu Railway Co. opened the Hamaotsu - Awazu section, dual track and electrified at 600 VDC, in 1913, and extended the line to Ishiyamadera (as single track) the following year.

The Hamaotsu - Miidera section opened in 1922 (dual track electrified), and in 1927 the company merged with a tourist boat operator to become the Biwako Railway & Steamship Co., which extended the line to Sakamoto the same year.

Keihan acquired the company in 1929 (and divested the steamship component immediately), connecting the line to its Keishin line in 1939.

The Awazu - Ishiyama section was duplicated in 1943, but in 1945 the Sakamoto - Shigasato section was returned to single track and the rails recycled for the Japanese war effort. The dual track was reinstated in 1947.

The voltage was increased to 1500 VDC in conjunction with the voltage upgrade on the Keishin line.
