'''Veatchite''' is an unusual strontium borate, with the chemical formula Sr<sub>2</sub>B<sub>11</sub>O<sub>16</sub>(OH)<sub>5</sub>·H<sub>2</sub>O. There are two known polytypes, veatchite-A and veatchite-p.<ref>Grice J D, Pring A (2012) Veatchite: structural relationships of the three polytypes, American Mineralogist 97, 489-495</ref>

Veatchite was discovered in 1938, at the Sterling Borax mine in Tick Canyon, Los Angeles County, California. Veatchite is named to honor John Veatch, the first person to detect boron in the mineral waters of California.
