Silvestro Valiero or Valier (Venice, 28 March 1630 – Venice, 7 July 1700) was the 109th Doge of Venice, reigning from his election on 25 February 1694 until his death six years later.
The Morean War between the Republic of Venice and the Ottoman Empire, which had been ongoing since 1684, came to an end during Valiero's reign as Doge, in January 1699.
