Aguilcourt is 2 km south of the town of Guignicourt. From Guignicourt the commune can be reached by road D62 which runs from the north-west border of the commune through the village and continues to Orainville in the south-east. Highway D622 runs south-west from the village to Cormicy. The western edge of the commune is traversed by the A26 autoroute (E17) but the nearest exit is Exit 14 north of the commune and west of Guignicourt. Some 200m north-east of the town is the Grand Marais railway station just outside the border of the commune. From here trains run north to Guignicourt and south to Loivre.[3]
The Suippe river forms most of the commune's northeastern border.
