We have trapped rubidium atoms in the magnetic field produced by a superconducting atom chip operated at liquid helium temperatures. Up to 8.2x10{sup 5} atoms are held in a Ioffe-Pritchard trap at a distance of 440 {mu}m from the chip surface, with a temperature of 40 {mu}K. The trap lifetime reaches 115 s at low atomic densities. These results open the way to the exploration of atom-surface interactions and coherent atomic transport in a superconducting environment, whose properties are radically different from normal metals at room temperature.
