Sillénite or sillenite is a mineral with the chemical formula Bi12SiO20. It is named after the Swedish chemist Lars Gunnar Sillén, who mostly studied bismuth-oxygen compounds. It is found in Australia, Europe, China, Japan, Mexico and Mozambique, typically in association with bismutite.

Sillenites refer to a class of bismuth compounds with a structure similar to Bi12SiO20, whose parent structure is γ-Bi2O3, a meta-stable form of bismuth oxide. The cubic crystal sillenite structure is shared by several synthetic materials including bismuth titanate and bismuth germanate. These compounds have been extensively investigated for their non-linear optical properties.
