The entire stretch of the line was opened at once on April 1, 1927, by Odakyu Electric Railway. In 1942, Odakyu was forcibly merged by the government with Tokyu Corporation and the line was named the Tokyu Odawara Line. Tokyu was broken up in 1948 and the line was transferred to the newly refounded Odakyu.
Through operation to the Hakone Tozan Railway's Hakone Tozan Line began in 1950 once dual gauge trains were developed (the Hakone Tozan Line is 1,435 mm (4 ft 8 1⁄2 in), the Odawara Line 1,067 mm (3 ft 6 in)). A bypass track was laid in 1955 to Matsuda Station on the Gotemba Line of the then-Japanese National Railways, and limited express service through to the line started. To function as a bypass to central Tokyo, through service on the Eidan Subway (now Tokyo Metro) Chiyoda Line commenced in 1978 via Yoyogi-Uehara.
Long standing land acquisition issues stalled major track expansion work until the early 2000s, though the tracks had been congested since around since the 1970s. In 1985, plans were formed for a track upgrading project on the Odawara Line with construction to begin in 2013; the project is being carried out between Yoyogi-Uehara and Mukōgaoka-Yūen, quadrupling the Odawara Line trackage and stacking the tracks underground, allowing for increased express services. Originally a viaduct was planned but this was changed to underground tracks, and work on the tunnel between Setagaya-Daita and Higashi-Kitazawa is ongoing. In March 2013, Odakyū announced that the construction is projected to continue until 2018.
