A '''regiment''' is a [[military unit]]. Its role and size varies markedly, depending on the country, [[military service|service]], or [[administrative corps|specialisation]].

In [[Middle Ages|Medieval Europe]], the term "regiment" denoted any large body of [[line regiment|front-line]] soldiers,<ref>Page 39, Vol. XXIII, Encyclopædia Britannica, 11th Edition.</ref> recruited or conscripted in one geographical area, by a leader who was often also the [[feudal lord]] ''in capite'' of the soldiers. Lesser barons of knightly rank could be expected to muster or hire a [[Company (military unit)|company]] or [[battalion]] from their manorial estate.

By the end of the 17th century, infantry regiments in most European armies were permanent units, with approximately 800 men and commanded by a [[colonel]].
