  We explore noncommutative D-branes in the AdS_5xS^5 background from the
viewpoint of \kappa-invariance of a covariant open string action in the
Green-Schwarz formulation. Boundary conditions to ensure the \kappa-invariance
of the action lead to possible configurations of noncommutative D-branes. With
this covariant method, we derive configurations of 1/4 BPS noncommutative
D-branes. The resulting D-branes other than D-string are 1/4 BPS at any places,
and the D-string is exceptional and it is 1/2 BPS at the origin and 1/4 BPS
outside the origin. All of them are reduced to possible 1/4 BPS or 1/2 BPS AdS
D-branes in the commutative limit or the strong magnetic flux limit. We also
apply the same analysis to an open superstring in the pp-wave background and
derive configurations of 1/4 BPS noncommutative D-branes in the pp-wave. These
D-branes consistently related to AdS D-branes via the Penrose limit.
