'''탄산 바륨'''({{lang|en|Barium carbonate}} 화학식:[[바륨|Ba]][[탄소|C]][[산소|O<sub>3</sub>]])은 [[바륨]]의 [[탄산염]]으로 '''독중석'''(毒重石), '''독중토석'''(毒重土石), '''위더라이트'''(Witherite)라고도 한다.

독성이 조금 있으며, [[유리]] 및 [[도예|요업]] 제품의 제조, [[쥐약]] 등에 쓰인다.

물에 녹지는 않지만, [[탄산염]]이기 때문에 [[위산 (소화계)|위산]]과 만나면 반응하여 [[이산화 탄소]]가 빠져나가면서 바륨이 용해되므로 [[조영제]]로 사용하여서는 절대 안된다.
