High-resolution measurements of the neutron total and capture cross sections have been performed on the separated isotope <sup>67</sup>Zn in the energy range from a few keV to about 1 MeV using the neutron time of flight technique and the pulsed Oak Ridge Electron Linear Accelerator. From R-matrix analysis of the total cross section data up to approximately 180 keV and least-squares fitting of capture data up to approximately 24 keV, values of E<sub>0</sub>, g Gamma <sub>n</sub>, J<sup>pi </sup> and Gamma <sub>gamma 0</sub> for resonances have been obtained. These results have provided the following values of average quantities: (S<sub>0J=2</sub>(*10<sup>4</sup>)=(1.35+or-0.15), S<sub>0J</sub>k=3(*10<sup>4</sup>)=(2.23+or-0.34) and S<sub>0J=2.3</sub>(*10<sup>4</sup>)=(1.86+or-0.20) up to 180 keV), (D<sub>0J=2</sub>=(1.09+or-0.06) keV, D<sub>0J=3</sub>=(0.83+or-0.04) keV and D<sub>0J=2.3</sub>=(413+or-28) eV up to 50 keV), (S<sub>1</sub>(*10<sup>4</sup>)=(0.72+or-0.07) and D<sub>1</sub>=(137+or-14) eV up to 24 keV). The value of average radiation width is (0.44+or-0.06) eV for 47 s-wave resonances up to approximately 24 keV.
