The glabella, in humans, is the area of skin between the eyebrows and above the nose. The term also refers to the underlying bone that is slightly depressed, and joins the two brow ridges. It is a cephalometric landmark that is just superior to the nasion.{{Cite web|url=https://www.researchgate.net/figure/268253842_Cephalometric-landmarks-Glabella-GL-the-most-prominent-or-anterior-point-in-the|title=Figure 3.

Etymology
The term for the area is derived from the Latin {{wikt-lang|la|glaber}}, "smooth", feminine of glabellus, "hairless".{{MW|glabella}}
Function
The glabella is a key anatomical landmark used in craniofacial measurements, including interglabellar distance, which helps assess facial proportions in aesthetics and surgery. It also contributes to facial expressions through the action of muscles like the frontalis and orbicularis oculi.{{sfn|Walker|Chauhan|2023}}
In medical science
The skin of the glabella may be used to measure skin turgor in suspected cases of dehydration by gently pinching and lifting it. When released, the glabella of a dehydrated patient tends to remain extended ("tented"), rather than returning to its normal shape.{{Cite book|title=Pharmacology for Canadian health care practice|page=511|last=Lane.|first=Lilley, Linda|others=Lilley, Linda Lane, Snyder, Julie S., Swart, Beth, 1948-, Collins, Shelly Rainforth., Savoca, Diane.|isbn=9781771720663|edition=Third Canadian|location=Toronto|oclc=981956602|date = 2016-08-05}}
