Abstract
The structure, kinematics and dynamics of the Galactic stellar halo are rev iewed including evidence of substructure in the spatial distribution and ki nematics of halo stars. Implications for galaxy formation theory are subseq uently discussed; in particular it is argued that the observed kinematics o f stars in the outer Galactic halo can be used as an important constraint o n viable galaxy formation scenarios.
