Baliracq-Maumusson (French pronunciation: [baliʁak momysɔ̃]; Occitan: Valirac e Maumosson) is a commune of the Pyrénées-Atlantiques department in the Nouvelle-Aquitaine region of south-western France.

Baliracq-Maumusson is located some 45 km east by north-east of Orthez and 20 km south of Aire-sur-l'Adour. Access to the commune is by the D211 road from Lannecaube in the south which passes through the length of the commune along the eastern side to join the D41 just north of the commune. Access to the village of Baliracq is by Le Moulin road branching from the D211. The commune is mixed forest and farmland.

The Lées river forms the eastern border of the commune as it flows north to join the Adour near Aire-sur-l'Adour. The Gabassot forms the northern border of the commune as it flows east into the Lées. Two other streams rise in the commune and flow into the Lées.

According to Michel Grosclaude the name Baliracq probably came from a Latin man's name Valerus with the Gallo-Roman suffix -acum giving the "Domain of Valerus". For Maumusson he proposed a Gascon man's name: the nickname mau meaning "bad" combined with mus meaning "nose" and the suffix -on giving "unfriendly" or "sullen".

The commune has a number of buildings and structures that are registered as historical monuments:

• A Mill at Baliracq (1764)
• A Farmhouse at Baliracq-Bouquehort (19th century)
• The Coussié House at Maumusson-Tardan (1742)
• The Castéra House at Baliracq-Castéra (1742)
• The Lafon House at Maumusson-Crédey (17th century)
• The Sansot House at Maumusson-Sansot (19th century)
• The Chateau de Milly at Maumusson-Florence (18th century)
• Houses and Farms (18th-19th century)
• A Fortified Area (Middle Ages)
• A Fortified Complex (Prehistoric). At a place called Castera the topography has been visibly altered by the hand of man as evidenced by the presence of an ancient fortified complex with major embankments and a circular walkway which is still visible. This could be for high wooden stakes joined together because no stone remains have been found. The works could therefore date to the high Middle Ages although there could be prehistoric remains.

The Parish Church of Saint Peter (11th century) is registered as an historical monument. The Church contains many items that are registered as historical objects:

• Communes of the Pyrénées-Atlantiques department

• Baliracq-Maumusson on Géoportail, National Geographic Institute (IGN) website (in French)
• Baliracq and Maumußon on the 1750 Cassini Map
