The Ivanja Reka interchange (Croatian: Čvor Ivanja Reka) is a cloverleaf interchange east of Zagreb, Croatia.

[1] The interchange is a part of Pan-European corridors Vb and X.

[3] The interchange was completed at junction of the Slavonska Avenue—four lane road providing access to Zagreb, present-day A3 motorway section to Lipovljani, built in 1980, and a 22.15-kilometre (13.76 mi) section between the Lučko and Ivanja Reka interchanges, a section of the Zagreb bypass opened in 1981.

It was named after the nearby village of Ivanja Reka.

The interchange originally also included a four-lane road, later upgraded and renamed as A4 motorway connecting Varaždin.
