Ribnica (pronounced [ˈɾiːbnitsa]) is a small settlement on the right bank of the Reka River in the Municipality of Pivka in the Inner Carniola region of Slovenia.

The name Ribnica was originally a hydronym derived from the common noun riba 'fish', thus referring to a stream with many fish and, by extension, a settlement along such a stream.

Ribnica was formerly a hamlet of Mala Pristava. In 1994, territory from Nadanje Selo, Mala Pristava, Nova Sušica, and Stara Sušica was combined to create Ribnica as a separate settlement.

Ribnica is the site of two mass graves from the end of World War II. They both contain the remains of German soldiers that fell in May 1945. The Rebri Mass Grave (Slovene: Grobišče Rebri) lies at the end of a meadow 50 meters (160 ft) east of the houses at the main crossroads in the settlement, at the edge of the woods. The Loka Mass Grave (Slovene: Grobišče Loka) lies along the road from Ribnica to Buje about 340 meters (1,120 ft) northwest of the crossroads. The Loka Mass Grave contained the bodies of 31 soldiers killed on May 4, 1945, which were exhumed between September 6 and 13, 2017.
