Jean Le Veneur (died 8 August 1543), son of a Norman baron, was a French Abbot, Bishop, Courtier, royal official, and Roman Catholic cardinal.

At the age of twenty-four, Jean le Veneur became Archdeacon of Auge in the Church of Lisieux,[5] no doubt both under his uncle's patronage.

Le Veneur was elected Bishop of Lisieux on 2 October 1505, in succession to his maternal uncle; he remained in this position until 18 August 1539.

[12] In 1511 Bishop Le Veneur participated in the schismatic Council of Pisa, under the presidency of Cardinal Bernardino López de Carvajal[13] Jean le Veneur became the first Abbot Commendatory of the Abbey of Mont-Saint-Michel in 1524, by appointment of King Francis I in accordance with the Concordat between him and Pope Leo X of 1516.

When they sent their news to the Court, the King's mother, Louise of Savoy, wrote in reply demanding that they sent representatives to present their documents showing the grant of their privilege of election, and at the same time inviting them to submit their votes for Jean le Veneur.

They submitted their bulls, and received in return a letter from the King, expressing his desire that they choose Jean le Veneur.

[16] On 10 May 1517, the Bishop of Lisieux was present at the Coronation of Claude of Brittany as Queen of France in the royal Abbey of S. Denis by Cardinal Philippe de Luxembourg.

[17] On 4 March 1525 Bishop Le Veneur was named Lieutenant-General of the government of Normandie, by the King's brother-in-law Charles, Duc d'Alençon, the Governor of the province.

Probably in 1530, Jean Le Veneur followed his brother Ambroise as Abbot Commendatory of Notre-Dame de Lyre in the Diocese of Évreux.

Also in 1533 Le Veneur was appointed Abbot Commendatory of the Abbey of S. Fuscien aux Boix in the diocese of Amiens, which he held until his death in 1543.

[27] In 1539, seeing that the Collège Mignon was not being properly maintained, having no religious attention and having fewer bursars than the twelve which were required, the Cardinal undertook to reform the institution.

His cousin and friend Bishop Jacques d'Annebault took charge of his body, which was moved to Elbeuf on 14 August, and to Bec on the 15th, where it was kept until 3 September.
