The luminous infrared-selected quasar IRAS 13349+2438 was observed with XMM-Newton as part of the performance verification program. The spectrum obtained by the RGS exhibits broad and narrow absorption lines from highly ionized elements including hydrogen- and helium-like nitrogen, oxygen, and neon, and several iron L ions. Also shown in the spectrum is the first detection of an "unresolved transition array" of iron in a much cooler medium. We present a preliminary analysis of the RGS spectrum and discuss the structure and dynamics of the complex absorbing medium surrounding the active nucleus.
