We report the discovery of an X-ray pulsar AX J1740.1-2847 from the Galactic center region. This source was found as a faint hard X-ray object on 7-8 September 1998 with the ASCA Galactic center survey observation. Then, coherent pulsations of P=729+/- 14 sec period were detected. The X-ray spectrum is described by a flat power-law of 0.7 photon index. The large absorption column of \log N_H 22.4 (cm-2) indicates that AX J1740.1-2847 is a distant source, larger than 2.4 kpc, and possibly near at the Galactic center region. The luminosity in the 2-10 keV band is larger than 2.5* 1033 erg s-1, or likely to be 3.2* 1034 erg s-1 at the Galactic center distance. Although the slow pulse period does not discriminate whether AX J1740.1-2847 is a white dwarf or neutron star binary, the flat power-law and moderate luminosity strongly favor a neutron star binary.
