Antoine Havet, Latinized Havetius (died 1578), was the first bishop of Namur in the Habsburg Netherlands.

Showing aptitude for scholarship, he received a better education than his siblings, and was sent to school in Arras, where he joined the Dominican Order.

[1] Havet took part in the 23rd, 24th and 25th sessions of the Council,[2] and was on the committee that investigated Giovanni Grimani, patriarch of Aquileia, on suspicions of Lutheranism.

[1] After his return to the Low Countries, he was a keen supporter of a full and early introduction of the canons of the Council, without regard for local privileges.

[2] In July 1570, he held a diocesan synod in Namur, the statutes of which were published in Leuven in 1571 with Jan Bogard.
