Uranophane (Ca(UO2)2(SiO3OH)2·5H2O), also known as uranotile, is a rare calcium uranium silicate hydrate mineral that forms from the oxidation of other uranium-bearing minerals.

It has a yellow color and is radioactive.

Alice Mary Weeks, and Mary E. Thompson of the United States Geological Survey, identified uranophane in 1953.

[5] Classic samples have been produced at Madawaska Mine near Bancroft, Ontario.
