Giulio Nuciari (born 26 April 1960) is an Italian football coach and former player who played as a goalkeeper.
After a season as first-choice keeper for Monza, he then signed for Sampdoria, where he was again a backup, behind Gianluca Pagliuca (1989–1994) and then Walter Zenga (1994–1995).
In October 2001 he was surprisingly appointed head coach of Serie B club Cagliari, but he lasted only two months before being sacked on December of the same year.
In 2003, his former Sampdoria teammate Roberto Mancini called him to work as goalkeeping coach of his club Lazio.
Nuciari is the titular of an original record for Serie A, as player with the highest number of appearances on the bench (333).
