The Pazzi conspiracy (Italian: Congiura dei Pazzi) was a plot by members of the Pazzi family and others to displace the Medici family as rulers of Renaissance Florence.

On 26 April 1478 there was an attempt to assassinate Lorenzo de' Medici and his brother Giuliano. Lorenzo was wounded but survived; Giuliano was killed. The failure of the plot served to strengthen the position of the Medici. The Pazzi were banished from Florence.
