An effective interaction is derived for use in the full $\mathrm{pf}$ basis. Starting from a realistic G-matrix interaction, 195 two-body matrix elements and four single-particle energies are determined by fitting to 699 energy data in the mass range 47--66. The derived interaction successfully describes various structures of $\mathrm{pf}$-shell nuclei. As examples, systematics of the energies of the first ${2}^{+}$ states in the Ca, Ti, Cr, Fe, and Ni isotope chains and energy levels of ${}^{56,57,58}\mathrm{Ni}$ are presented. The appearance of a new magic number 34 is seen.
