'''Septum''' (dari [[bahasa Latin]] yang artinya sesuatu yang melingkupi, jamak: Septa) adalah pembatas yang memisahkan suatu rongga atau ruang. Sebagai contoh anatara lain:
* [[Nasal septum]]: dinding yang memisahkan rongga hidung kiri dan kanan,
* [[Cephalopod septa]]: dinding yang membatasi tiap rongga dalam cangkang binatang seperti [[nautilus]] atau bekicot.
* [[Interatrial septum]]: dinding yang memisahkan serambi kanan dan kiri jantung.
* [[Interventricular septum]]: dinding yang memisahkan bilik kanan dan kiri jantung.

Histological septa are seen throughout most tissues of the body, particularly where they are needed to stiffen a soft cellular tissue, and they also provide planes of ingress for small blood vessels. Because the dense collagen fibres of a septum usually extend out into the softer adjacent tissues, microscopic fibrous septa are less clearly defined than the macroscopic types of septa listed above. In rare instances, a septum is a cross-wall.
The septum is also found within the chambers of the heart. It provides strength to the walls of the heart and separates the left and right sides of the heart.
==Particle accelerators==
Septum magneta and electrostatic septum are two types of septa that can deflect an ejected beam while not affecting the orbiting beam. These devices are used with a circular particle beam accelerator to inject or eject a beam of particles to or from an accelerator.
==Brain physiology==
Part of the [[limbic system]] that regulates emotions and the ability to learn and control impulses as well as such drives as sex, hunger, thirst, aggression, and fear. The septum (or [[septal nuclei]]) in the brain is named for its approximate shape (partition). The septum is rich with nicotinic cholinergic receptors.
