  The proton drip line of (hyper)nuclei is examined within the framework of the
deformed Skyrme-Hartree Fock approach by adjusting the nuclear force parameters
to exactly reproduce the core binding energies. The impact of adding a
{\Lambda} hyperon in a s or p state is studied, and it is found that in some
cases the deformation effect facilitates the extension of the drip line by an
added p-state hyperon. However, no extension of the drip line is found for
s-state hypernuclei.
