Besides the village center the commune of Saint-Pardoux-la-Rivière comprises the following hamlets:

Beaumont, Bon Ombre, Bordessoule, Bos-Brûlat, Brande, Brin, Chaumeille, Chez Bathe, Chez Boissard, Chez Boutard, Chez Neymard, Jamaye, La Briderie, La Dorie, La Font du Prince, La Grange, La Nanotte, La Plassade, Langlade, Lapeyronnie, Le Buisson, Le Châtenet, Le Clos, Le Couvent, Le Maine, Le Mandereau, Le Queyroi, Le Petit Villars, Les Batisses, Les Combes, Les Granges, Les Rebières, Les Roches, Lescure, Maliba, Négrecombe, Neuil, Noujarède, Puy d'Arnac, and Puypelat.

. The northern boundary to Champs-Romain is formed by the river, which is occupying a narrow canyon. After initially following a southwesterly direction it then swings to the south. Before reaching the village the valley widens. Alongside a ford over the river Saint-Pardoux was founded.

A right tributary of the Dronne, the Ruisseau de Lachenaud, forms the western continuation of the northern boundary to Champs-Romain. Its course is directed to the southeast. Near the center of Saint-Pardoux the Dronne receives a left tributary, the Ruisseau de Chantres.

The topographically lowest point in the commune with 132 meters above sea level is situated at the southern exit of the Dronne near Jamaye, the highest point with 332 meters above sea level near Bos Brûlat in the very northeastern corner.

It underwent extensive renovation during the 19th century with the steeple being completely rebuilt. The Château de Vaugoubert at the Dronne also goes back to the 17th century. From an even older castle only the round tower is left.
