Temperature-dependent static magnetization, ac magnetic susceptibility, and electrical-resistivity measurements of single-crystal DyNi{sub 2}B{sub 2}C reveal bulk superconductivity below {ital T}{sub {ital c}}=(6.2{plus_minus}0.1) K. This {ital T}{sub {ital c}} is well below the Neel temperature {ital T}{sub {ital N}}=10.3 K. DyNi{sub 2}B{sub 2}C is the first {ital R}Ni{sub 2}B{sub 2}C compound with {ital T}{sub {ital c}}{lt}{ital T}{sub {ital N}}. The upper critical magnetic field {ital H}{sub {ital c}2}({ital T}) increases approximately linearly from zero at 6.2 K to {similar_to}5 kG at 2 K.
