Yttrium acetylacetonate is a coordination compound with the chemical formula Y(C₅H₇O₂)₃(H₂O)_x, or Y(acac)₃(H₂O)_x for short. The value of x can vary from 1 to 3.

Upon heating under vacuum, the hydrates convert to the oxo-cluster Y₄O(C₅H₇O₂)₁₀. This behavior is also observed for gadolinium acetylacetonate, europium acetylacetonate, lanthanum acetylacetonate, and erbium acetylacetonate.
