The former West Ham United man joins the newly-promoted Hornets on a three-year deal for a reported fee of £3m.
Behrami spent just one season in Germany, making 22 appearances in the Bundesliga.
As well as securing the future of several first-team players with new contracts, Watford have also signed Giedrius Arlauskis, Sebastian Prodl, Matej Vydra, Jose Holebas and Etienne Capoue this summer.
