François-Xavier Bustillo OFMConv (born 23 November 1968) is a French Catholic prelate of Spanish origin who has been the Bishop of Ajaccio in Corsica since 2021.

[4][5] Named Francisco-Javier Bustillo Rípodas[6][7] at his birth on 23 November 1968 in Pamplona in Navarre, Spain,[8] he was the eldest of four children.

[10] At age 17 he joined the Order of Conventual Franciscans in Padua, Italy, where he completed his work in philosophy and theology at the Istituto Teologico Sant'Antonio Dottore.

[3][14] In February 2022, after Paris-Match reported that Bustillo was one of the leading candidates for the position of Archbishop of Paris, he said he had not been contacted and that it was not Church practice to move a bishop so soon.

"[15] In April 2022, Pope Francis gave an Italian-language version of Bustillo's book Witnesses, Not Officials[b] to each of the priests attending the Chrism Mass in St. Peter's Basilica on Holy Thursday.

[22] In September 2023, the French Catholic magazine Golias described the charismatic activities and "misguided mysticism" of Franciscan Brother Daniel-Marie Thévenet as "bordering on charlatanism".

[7] Bustillo spent the day at Pope Francis' side when he visited Ajaccio on 15 December 2024 to address a symposium on Popular Religiosity in the Mediterranean.

[26] Bustillo was described as "media-savvy" for his organization of the visit[27] and Le Monde noted how he curated the image of Corsica he wanted the world to see–"good-natured and sunny" with "babies brandished to be blessed by the pope", "flocks of the faithful who knew the words to the songs", and "pilgrims who came with picnics in their backpacks"–in contrast to the celebrities who gathered in rainy Paris a week earlier to celebrate the reopening of Notre Dame.
