The Yamagata Shinkansen (Japanese: 山形新幹線) is a mini-Shinkansen route in Japan, operated by East Japan Railway Company (JR East). It provides service between Tokyo and Shinjō in Yamagata Prefecture over the tracks of the Tōhoku Shinkansen and the Ōu Main Line.

The term Yamagata Shinkansen refers to the segment that connects Fukushima and Shinjō. Because the Shinkansen trains share tracks with local trains running on conventional lines it is often referred to as a "mini-Shinkansen".
