Odawara-juku (小田原宿 Odawara-juku?) was the ninth of the fifty-three stations of the Tōkaidō. It is located in the present-day city of Odawara, Kanagawa Prefecture, Japan. It was the first post station in a castle town that travelers came to when they exited Edo (modern-day Tokyo) in Edo period Japan.
Odawara-juku was established between the mountains of Hakone and Sagami Bay, near Odawara Castle. Located near the banks of the Sakawa River, Odawara-juku was a famous post station. It is said to hold the remains of Lady Kasuga.
