The Ural-377 is a truck developed from 1958 alongside the Ural-375 by the UralAZ. The main difference with its twin is the drivetrain which is 6×4, as the Ural-377 is supposed to be more of a road truck.

It was tested between 1961 and 1964 and started mass production in 1965¹⁾ up to 1983. It was a civilian truck and has had its batch of variants over time.
