Novi Zagreb – istok (Croatian pronunciation: [nôʋiː zǎːgreb ǐstok], "New Zagreb – east") is a district in Zagreb, Croatia. Within this district in the neighborhood of Travno lies Mamutica, which was built to be the largest communal housing block in southeast Europe. Mamutica towers above other blocks of flats so that the impression is given that it must be on a hill even though the entire area is a flat plain.

In the north of Novi Zagreb, just south of the river Sava, is lake Bundek. Though originally a gravel pit, nature has reclaimed it and it is now an area of woods, brushwood and ponds. In the year 2006, lake Bundek was hastily decorated; it now has a beach and some amusing accessories.

Novi Zagreb-istok has the status of a city district (gradska četvrt) and as such has an elected council.

Novi Zagreb-istok had 59,055 residents during the 2011 census.
