Rooksbury Mill is an old watermill on the River Anton in Andover, Hampshire, England, and a Grade II listed building.

[3] On the afternoon of Friday 29 May 1812, a barn at Rooksbury Mill was struck by lightning and set ablaze.

Although there were numerous people present, nothing could be done to extinguish the blaze, which also threatened the adjacent house and the Mill building, all being in the ownership of John Rawlinson, Esq.

The barn eventually collapsed, destroying a large quantity of wheat and a threshing machine that had been in use at the time.

The Test Valley Borough Council sold the building in 2002, shortly after it had been devastated by fire following an arson attack.
