Vuvuzelas have been banned from all Uefa-sanctioned football matches such as Euro 2012 qualifiers and Champions League games.
The horns were popular at the World Cup in South Africa but critics say they drowned out fan singing and atmosphere.
A Uefa statement says the move was taken for reasons related to Europe's football culture and tradition.
Several football teams in England and also other sporting events and musical festivals had already banned the instruments, while some others left it up to fans to decide, but Uefa is the first major footballing body to impose a ban on its members.
