The Odakyu 10000 series HiSE (小田急10000形, Odakyū 10000-gata) (High-decker/High-grade/High-level Super Express) was an electric multiple unit (EMU) train type operated by the Odakyu Electric Railway on Romancecar services in the Tokyo area of Japan between 1987 and 2012.

Sets number 2 and 3 were donated to the Nagano Electric Railway in 2005.

They were converted to 4-car 1000 series sets at Nippon Sharyo manufacturing factory in Toyokawa, Aichi Prefecture.

The two remaining 10000 series HiSE sets were withdrawn by Odakyu on 16 March 2012.
