Kobilje Creek (Hungarian: Kebele,Slovene: Kobiljski potok or Kobiljanski potok) is a brook in northeastern Slovenia and western Hungary. The brook is 33 kilometres (21 mi) long; 24 km (15 mi) of the course is in Slovenia. Its source is at Kamenek Hill (391 metres or 1,283 feet) and it flows through Kobilje, crosses the Slovenian–Hungarian border, returns to Slovenia, and joins the Ledava from its left side. It is the longest tributary of the Ledava.
Kobilje Creek was first mentioned in 1208 as aguam Kobula. In 1236, it was mentioned as Kebela, in 1329 as Kebelie, and in 1338 as Kebele. Its Slovene name is derived from Slavic *kobyla 'mare'. The current Slovene names for the stream are derived from the settlement of Kobilje. However, based on medieval sources, it was originally called *Kobilja (voda) (literally, 'mare stream') and the settlement of Kobilje was named after it. The stream was then later renamed after the settlement.
