Seichō-ji (清澄寺^?), also known as Kiyozumi-dera Temple is a Nichiren Shū temple located in the city of Kamogawa in Chiba Prefecture, Japan. Along with Kuon-ji in Yamanashi Prefecture, Ikegami Honmon-ji in the south of Tokyo, and Tanjō-ji also in Kamogawa City, Seichō-ji is one of the "Four Sacred Places of Nichiren Shū."

The Buddhist priest Nichiren was once educated at the temple, and was chosen at one time to be a successor to its priesthood before he began his own ministry which later became Nichiren Buddhism. At the time, the temple was dedicated to the Pure Land sect, prior to being a Tendai temple, then later changed into Shingon, and now presently designated a Nichiren Shu temple.

Seichō-ji is located on Chiba Prefecture's second highest mountain, the 310-meter high Myōken-san. The temple grounds are within the borders of the Minami Bōsō Quasi-National Park. Myōken-san is the source of two of the Bōsō Peninsula's important rivers, the Yōrō River and the Obitsu River. The translation of the temple's name, meaning "clear, serene" probably originated in these natural features—Water running under the numerous daimyō oaks in the area.
