Lanthanum carbonate, La₂(C O₃)₃, is the salt formed by lanthanum(III) cations and carbonate anions. It is an ore of lanthanum metal, along with monazite.

Lanthanum carbonate is used as a starting material in lanthanum chemistry, particularly in forming mixed oxides, for example

for production of lanthanum strontium manganite, primarily for solid oxide fuel cell applications;
for production of certain high-temperature superconductors, such as La_2-xSr_xCuO₂.

Lanthanum carbonate is used in medicine as a phosphate binder^[1]. As a medication it is sold under the trade name Fosrenol by the pharmaceutical company Shire Pharmaceuticals. It is prescribed for the treatment of hyperphosphatemia, primarily in patients with chronic kidney disease. It is taken with meals and binds to dietary phosphate, preventing phosphate from being absorbed by the intestine. For cats suffering from hyperphosphatemia it is available under the trade name Renalzin by Bayer Animal Health.^[2]

Lanthanum carbonate is also used for the tinting of glass, for water treatment, or as a catalyst for hydrocarbon cracking.
