  The prospects of experimental detection of $CP$ violation at $e^+e^-$ and
$pp/p\overline{p}$ colliders are reviewed. After a general discussion on the
quantities which can measure $CP$ violation and on the implications of the
$CPT$ theorem, various possibilities of measuring $CP$ violation arising
outside the standard model are taken up. $CP$ violation in leptonic processes,
especially polarization effects in $e^+e^-\rightarrow l^+l^-$ are discussed
next. $CP$ violation in $t\overline{t}$ and $W^+W^-$ production and decay is
also described. (Based on talk presented at the WHEPP3, Madras, January 1994).
