Zagreb bypass (Croatian: obilaznica, zaobilaznica) is a U-shaped motorway partially encircling Zagreb, Croatia. The largest part by far, between Jankomir and Ivanja Reka interchanges, was built between 1977 and 1979, while the Ivanja Reka – Sveta Helena section was built between 1996 and 1999. The bypass is 48.9 kilometres (30.4 mi) long, tracing around the city from the northwestern suburb of Zaprešić to Sveta Helena in the northeast. The bypass crosses the Sava River twice and comprises a bridge across the Sava-Odra floodwater overflow canal. As the busiest sections between Jankomir and Buzin interchanges carry traffic volume of approximately 45,000 AADT, it is the most heavily used motorway sector in Croatia.

Zagreb bypass is not designated as a separate motorway with a distinct motorway number, rather it consists of sections of three motorways:

Those motorway sections are concurrent with sections of the D1 and D3 state roads as well as European routes E59, E65, E70 and E71.

The bypass currently comprises four traffic lanes along its entire length, with an emergency lane in each direction. In its current form, the Zagreb bypass has a small number of interchanges spaced widely apart. For example, the current Zaprešić interchange extends a trip from Zaprešić to Zagreb via the bypass by 4.5 km (2.8 mi). The last new interchange was built in 2007–2008 at Kosnica in the southeast, to connect the Homeland Bridge and Zagreb via Radnička cesta (Ž1029).
