Radfjorden is a fjord in Hordaland county, Norway. The long fjord runs between the islands of Radøy (in Radøy and Lindås municipalities) and Holsnøy (in Meland municipality). The northwestern end of the fjord is called the Mangerfjorden and it flows out into the Hjeltefjorden. The southeastern end of the fjord is also known as the Kvernafjorden, and it flows out into the confluence of three other fjords: Salhusfjorden, Osterfjorden, and Sørfjorden. The fjord is a good fishing area, and it is also good for catching crab and shrimp.
