A lancet window is a tall, narrow window with a sharp pointed arch at its top.[http://freenet.buffalo.edu/bah/a/DCTNRY/l/lancet.html Buffalo Architecture] {{webarchive|url=https://web.archive.org/web/20060905183913/http://freenet.buffalo.edu/bah/a/DCTNRY/l/lancet.html |date=5 September 2006 }}, Retrieved 24 October 2006 This arch may or may not be a steep lancet arch (in which the compass centres for drawing the arch fall outside the opening). It acquired the "lancet" name from its resemblance to a lance.{{Cite web |title=Lancet window {{!}} Gothic, Gothic Revival & Stained Glass {{!}} Britannica |url=https://www.britannica.com/technology/lancet-window |access-date=2023-08-16 |website=www.britannica.com |language=en}} Instances of this architectural element are typical of Gothic church edifices of the earliest period. Lancet windows may occur singly, or paired under a single moulding, or grouped in an odd number with the tallest window at the centre.

The lancet window first appeared in the early French Gothic period (c. 1140–1200), and later in the Early English period of Gothic architecture (1200–1275). So common was the lancet window feature that this era is sometimes known as the "Lancet Period".{{Cite web |last=Express |first=Britain |title=Gothic Architecture in England |url=https://www.britainexpress.com/History/Gothic-architecture.htm |access-date=2023-08-16 |website=Britain Express |language=en}}

The term lancet window is properly applied to single-light windows of austere form, without tracery. Paired windows were sometimes surmounted by a simple opening such as a quatrefoil cut in plate tracery. This form gave way to the more ornate, multi-light traceried window.
