A stenosis (plural: stenoses; from Ancient Greek στένωσις, "narrowing") is an abnormal narrowing in a blood vessel or other tubular organ or structure. It is also sometimes called a "stricture" (as in urethral stricture).

Stenoses of the vascular type are often associated with a noise (bruit) resulting from turbulent flow over the narrowed blood vessel. This bruit can be made audible by a stethoscope. Other, more reliable methods of diagnosing a stenosis are imaging methods including ultrasound, Magnetic Resonance Imaging/Magnetic Resonance Angiography, Computed Tomography/CT-Angiography which combine anatomic imaging (i.e. the visible narrowing of a vessel) with the display of flow phenomena (visualization of the movement of the bodily fluid through the bodily structure).
