Reningelst is a rural village in the Belgian province of West Flanders, and a "deelgemeente" of the municipality Poperinge.

The church was burned down in 1623 by Ypres Geuzen and was rebuilt to it current, Gothic architecture circa 1623.

On September 6, 1793 the fortified castle was completely burnt down, on the orders of General Van Damme.

Until the 1960s a brewery on the village square brewed Roökop (translated from Flemish: Red Head).

The beer has now gone, but the brewery still stands (though part of it in ruins), now as the local cultural centre, also called Rookop.

Since 2006 it is also the location for the annual "Troost van Schoonheid" (Comfort of Beauty) one-day music and poetry festival.
