The Caddo Conference Organization promotes and stimulates interest in the archeology, history, and ethnology of the Caddo arehceological region. They also advocate for, and assist in the preservation and conservation of archeological data and resources relating to Caddo Area studies or sacred to the Caddo people.

The Caddo Conference Organization holds an annual meeting where posters and papers are presented. All members are welcomed and encouraged to submit a poster or paper. The first Caddo Conference was held in Norman, Oklahoma in 1946. It was held sporadically until 1970 when it was consistently held to 2020. The 2021 conference was cancelled due to the COVID-19 pandemic. There is generally a shift in holding the conference in the four states which the Caddo occupied—namely, Oklahoma, Texas, Louisiana, and Arkansas.

The Caddo Archeology Journal is devoted to the anthropology, history, geography, and current activities of the Caddo Nation, an American Indian group with a historical range covering the four-state area of Texas, Louisiana, Arkansas, and Oklahoma. The journal began as the Caddoan Archeology Newsletter in 1989 and in 1996 the name changed to simply Caddoan Archeology. Tim Perttula was founder and editor from 1989 until 1993 when Lois Albert became editor. Tim Perttula again resumed his editorial role in 2002. In 2003 the name was changed to Caddoan Archeology Journal, and in 2006 the name was changed again to Caddo Archeology Journal. Along with archeology, articles related to the ethnography, language, history, geography, and current activities of the Caddo Nation are encouraged. Book reviews are also included in the journal. The journal is published once a year in March.
