Šentjakob ob Savi is a clustered settlement on a terrace above the Sava River east of Črnuče. The old channel of the Sava can be seen in the southern part of the village, where the river flowed before it was regulated during construction of the Austrian Southern Railway. The soil is sandy and fertile. The A1 Freeway runs directly east of the old village center.
