  We review the present status of the Standard Model of CP violation, which is
based on a complex phase in the Cabibbo-Kobayashi- Maskawa (CKM) matrix. So far
CP violation has been observed only in $K^0-\Kbar$ mixing, consistent with a
sizable phase. The implications of future CP nonconserving measurements in $K$
and $B$ decays are discussed within the model. Direct CP violation in $K\to
2\pi$ may be observed in the near future, however this would not be a powerful
test of the model. $B$ decays provide a wide variety of CP asymmetry
measurements, which can serve as precise tests of the Standard Model in cases
where the asymmetry is cleanly related to phases of CKM matrix elements. Some
of the most promising cases are discussed.
