'''Kalsium oksalat''' adalah garam [[kalsium]] [[oksalat]] dengan rumus kimia CaC<sub>2</sub>O<sub>4</sub>·(H<sub>2</sub>O)<sub>x</sub>, di mana x bervariasi dari 0 hingga 3. Semua bentuk tidak berwarna atau putih. Monohidrat terjadi secara alami sebagai mineral whewellite, membentuk kristal berbentuk amplop, yang dikenal pada tumbuhan sebagai raphides. 

Dihidrat yang lebih jarang (mineral: weddellite) dan trihydrate (mineral: caoxite) juga dikenal. Kalsium oksalat merupakan penyusun utama batu ginjal manusia. Kalsium oksalat juga ditemukan di beerstone, skala yang terbentuk pada wadah yang digunakan di tempat pembuatan bir.
