Sidi Kacem (Arabic: سيدي قاسم|sidi qasəm) is a city in Rabat-Salé-Kénitra, Morocco. It is the capital of Sidi Kacem Province.
During the French period, the city was called Petitjean, in reference to a French captain who was killed in May 1911 during the "pacification" of Morocco. The French started oil drilling exploration in the vicinity of Sidi Kacem in 1934; production of crude oil began locally in 1939.[2]
Slightly to the south of Sidi Kacem lies Volubilis, which was in antiquity an important Roman town near the westernmost border of the Roman Empire. It was built on the site of a previous Mauretanian settlement from the third century BC, if not earlier.[3]

Sidi Kacem is located along Morocco's national ONCF railway line and was considered a crossroads because passengers going to the North had to switch trains in its station. This is not longer the case as the ONCF has constructed a direct railway which doesn't cross Sidi Kacem.
The town has a local bus station, which serves all the regions of the country, in addition to multiple grand-taxis stations, for the nearest cities and villages.
