Bedek Stream (Bulgarian: Бедечки поток, romanized: Bedechki potok, IPA: [bɛˈdɛt͡ʃki poˈtɔk]) is the 3.2 km long stream on eastern Byers Peninsula, Livingston Island in the South Shetland Islands, Antarctica draining the lakes of Oread and Montemno. It flows northwards along the west side of Urvich Wall and the east side of Tsamblak Hill, crosses Robbery Beaches and empties into Barclay Bay just east of Sparadok Point. The area was visited by early 19th century sealers.

Bedek is a Thracian toponym preserved in the names of Big and Little Bedek Peaks, and Bedechka River in Central Bulgaria.
