Ryūtaku-ji (龍澤寺) is a Buddhist temple belonging to the Myōshin-ji branch of the Rinzai school of Japanese Zen, Buddhism located in Mishima, Shizuoka Prefecture, Japan.

During the mid-twentieth century Ryūtaku-ji was led by a number of influential abbots, who encouraged and supported the study of Zen by Westerners.

Most notable among these was Soen Nakagawa who was highly regarded as a calligrapher and haiku poet, often referred to as the "20th Century Bassho."

Kyudo Nakagawa was the abbot of Ryūtaku-ji (as well as Soho Zendo on West Broadway in New York City) up until his death in December 2007.

Since January 2008, the new abbot of Ryūtaku-ji is Eizan Goto, who is also the Zen Master of Centre Assise, a meditation center near Paris (France).
