Anterior compartment of thigh
Cross-section through the middle of the thigh. (Anterior compartment is at upper left.)
Latin	compartimentum femoris anterius
Gray's	subject #128 468
Artery	femoral artery
Nerve	femoral nerve

The anterior fascial compartment of thigh contains the knee extensors and hip flexors.

It contains the following five muscles:^[1]

• sartorius (the longest muscle in the human body)
• quadriceps (rectus femoris, vastus lateralis, vastus intermedius, vastus medialis)

The articularis genu is sometimes included in this group.^[2]

The iliopsoas is sometimes considered a member of this group;^[2][3] however, the psoas portions do not share the same innervation.
