Cheralite is an anhydrous phosphate mineral with the ideal chemical formula CaTh(PO₄)₂.^[1]^[2] It is isomorphous with huttonite and monazite. It can be regarded as the product of the complete cationic substitution in the system:

2 LREE³⁺ ↔ Ca²⁺ + Th⁴⁺.

It was previously known under the name brabantite.
