The Hers-Vif ("Live Hers", as opposed to the slower flowing Hers-Mort, "Dead Hers"), also named Grand Hers or simply Hers, is a {{convert|135|km|mi|adj=on}} long river in southern France, right tributary of the Ariège.

The Hers-Vif rises at an elevation of about {{convert|1500|m|ft}} near the Chioula Pass of the Pyrenees, approximately {{convert|6|km|mi|0}} north of Ax-les-Thermes. It is the major tributary of the Ariège into whose right bank it flows {{convert|2|km|mi}} upstream from Cintegabelle in the Haute-Garonne.

It flows some {{convert|30|km|mi}} through the Pyrenees, descending {{convert|1100|m|ft}} to the village of Peyrat, where it reaches a piedmont plain. Its valley widens as it traverses the plain, reaching the medieval city of Mirepoix, which marks the start of its lower valley.

Several rivers flow into it:

From the Pyrenees: the Lasset; the Fontaine de Fontestorbes; the Touyre
From the piedmont plain and hills: the Blau and the Douctouyre;
From the hills of Lauragais and Razès: the Ambronne and the Vixiège.

Departments and towns along its course are:

Ariège: Prades, Bélesta, La Bastide-sur-l'Hers, Mirepoix, Mazères
Aude: Comus, Chalabre
Haute-Garonne: Calmont

Floods

The Hers is probably known as vif (intense or rapid in this context) because of its sometimes spectacular floods – that of 16 June 1289 having entirely destroyed Mirepoix. More recently, there have been:

23 June 1875: estimated flow rate of {{convert|1500|m3/s|cuft/s}} at Mazères;
6 February 1919: estimated flow rate of {{convert|600|to|800|m3/s|cuft/s}} at Mazères;
19 May 1977: estimated flow rate of {{convert|1070|m3/s|cuft/s}} at Mazères;
16 January 1981: estimated flow rate of {{convert|1100|m3/s|cuft/s}} at Mazères;
11 June 2000: estimated flow rate of {{convert|500|m3/s|cuft/s}} at Mazères;
24 January 2004: estimated flow rate of {{convert|500|m3/s|cuft/s}} at Mazères.
