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 $\mathrm{\Lambda }$ hyperon in an $s$ 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.
