Martin was the count of Laon in the late second half of the 7th century.
After the assassination of King Dagobert II of Austrasia in 679, Count Martin (dux Martinus) and Pepin of Herstal were the leading noblemen of Austrasia and led the resistance against Neustrian mayor Ebroin, who had designs on all of Francia.
Pepin escaped to Cologne; Martin made it back to Laon, where he was slain on Ebroin's orders.
It has been suggested by some historians that Martin was the brother of his ally, Pepin of Herstal.
Martin has also been suggested as the husband of Bertrada of Prüm which would make him father of Charibert of Laon, himself a grandfather of Charlemagne.
