The Sony Ericsson Xperia Active is a smartphone produced by Sony Ericsson.

It contains similar hardware as other 2011 Xperia phones in a smaller package. The phone is marketed towards people with an 'active lifestyle', hence the name, and comes with a scratch resistant screen, dust and water resistant casing and pre-loaded fitness applications.
