Аннотация: We determine the location of the proton drip line for light Λ and ΛΛ hypernuclei. While it is already known for 1≤𝑍≤4, our main focus is the 5≤𝑍≤8 range, and further conclusions are drawn for proton-rich Λ hypernuclei up to 𝑍=20. Λ binding energies from the Skyrme-Hartree-Fock calculation and the energies of unstable nuclei known experimentally are used. It is shown that 9ΛC, 10ΛΛC and 14ΛΛO with unstable nuclear cores are bound whereas 8ΛB, 12ΛN, 13ΛO and 13ΛΛN are not. Boundness of 9ΛΛB remains questionable. Among heavier systems, 17ΛF, 20ΛNa and 20ΛMg are shown to be the possible candidates for bound hypernuclei.
