Tateyama Domain was a feudal domain under the Tokugawa shogunate of Edo period Japan, located in Awa Province, Japan. It was centered on Tateyama Castle in what is now the city of Tateyama, Chiba.

Awa Province was a province of Japan in the area of modern Chiba Prefecture. It lies on the tip of the Bōsō Peninsula (房総半島), whose name takes its first kanji from the name of Awa Province and its second from Kazusa and Shimōsa Provinces. Its abbreviated form name was Bōshū (房州) or Anshū (安州). Awa Province in Shikoku phonetically has the same name, but is written with different kanji (阿波国). Awa is classified as one of the provinces of the Tōkaidō. Under the Engishiki classification system, Awa was ranked as a "middle country" (中国) and a "far country" (遠国).
