The Seville European Film Festival (SEFF; ) is an annual film festival dedicated to European cinema held in November in Seville, Spain, since 2004.
The festival is an initiative of the Instituto de la Cultura y las Artes de Sevilla (; ICAS), which depends on the Ayuntamiento de Sevilla. It is supported by the ICAA and the sub-programme Europe Creative MEDIA. The festival has also traditionally served as staging ground for the announcement of the nominations to the European Film Academy's European Film Awards. Since 2013, it enjoys the collaboration from Filmin.
The top prize awarded at the festival is known as the 'Golden Giraldillo' ().
The first edition took place on 6–13 November 2004. Festival programming director José Luis Cienfuegos resignated in April 2023. In August 2023, the new municipal administration determined to postpone the 20th edition, due to be held in early November 2023, to the Spring of 2024, in order to make room for the celebration of the 24th Annual Latin Grammy Awards. Such plans were rolled back days later, with the festival returning to a November 2023 date, but later in the month and featuring a shorter format.
