$^{160}\mathrm{Gd}(n,{n}^{\ensuremath{'}}\ensuremath{\gamma})$ experiments were performed with accelerator-produced monoenergetic neutrons. Excitation functions at neutron energies from 1.5 to 2.8 MeV aided in the placement of $\ensuremath{\gamma}$ rays in the level scheme and angular distributions at three neutron energies resulted in the determination of 28 excited-level lifetimes or limits in $^{160}\mathrm{Gd}$, including the lifetimes of several negative-parity levels attributed to octupole vibrations.
