The magnetic order of Pr in nonsuperconducting PrBa{sub 2}Cu{sub 3}O{sub 7} has been studied by specific-heat, susceptibility, and neutron-diffraction measurements. The basic ordering consists of a simple antiferromagnetic arrangement, with a saturated moment of 0.24{mu}{sub {ital B}} and a Neel temperature {ital T}{sub {ital N}} of {similar to}17 K, which is two orders of magnitude higher than expected from either dipolar or Rudeman-Kittel-Kasuya-Yosida interactions alone. The small moment, along with the large value of the low-temperature electronic specific-heat coefficient {gamma} of 196 mJ/mol K{sup 2}, suggests that there is substantial {ital f}-electron character at the Fermi level.
