The Kelvin--Helmholtz instability is examined for magnetized plasmas where the effective ion Larmor radius, {ital u}/{omega}{sub {ital ci}}, is larger than the velocity shear scale ({ital u} is the flow speed and {omega}{sub {ital ci}} is the ion gyrofrequency). In this parameter regime, the properties of the instability are modified as compared with the small Larmor radius case and a new short wavelength branch is introduced. The instability properties and some applications are discussed.
