Fantaisie militaire (Military fantasy) is the tenth studio album by the French rock musician Alain Bashung, released in January 1998 by Barclay Records.

For this album, Bashung worked with the English record producer and engineer Ian Caple and with artists such as the Valentins, Rodolphe Burger, Joseph Racaille and Adrian Utley of Portishead.

Fantaisie militaire marked a turn in Bashung's career.

The Belgian rock historian Gilles Verlant included the album in his book La discothèque parfaite de l'odyssée du rock,[3] lauding it as a "chef d'œuvre" and the "shining diamond of the winter of 1998".

He added that the album showed "Bashung mix the sounds and his inspiration with a perfect mastery of studio incidents" and that "its precision is that of a goldsmith, a jeweler, a maniac watchmaker".
