Former coach Inter and Napoli moved to the English Premier League after the end of last season.
In the current drawing of the national championship, Watford managed to keep a residence permit in the elite, for the tour until the end of the competition being on the 16th place. Nevertheless, the club management found such results unsatisfactory, having made the decision to part with Mazzarri.
"After the club's management discussed the club's goals for the future with Walter Mazzarri, it was decided that the head coach will leave his post at the end of the 2016/2017 season," said Hornets executive director Scott Duuxbury.
"We thank Walter and his team for the contributions they have made to the development of Watford over the past year".
Under the leadership of the Italian Watford lost in 20 of the 39 matches in all tournaments.
The final match at the helm of the team Matzarri will hold against Manchester City.
