Aims. We carried out a radial-velocity survey to search for planets aroundmetal-poor stars. In this paper we report the discovery of two planets aroundHIP 11952, a metal-poor star with [Fe/H]= -1.9 that belongs to our targetsample. Methods. Radial velocity variations of HIP 11952 were monitoredsystematically with FEROS at the 2.2 m telescope located at the ESO La Sillaobservatory from August 2009 until January 2011. We used a cross-correlationtechnique to measure the stellar radial velocities (RV). Results. We detected along-period RV variation of 290 d and a short-period one of 6.95 d. Thespectroscopic analysis of the stellar activity reveals a stellar rotationperiod of 4.8 d. The Hipparcos photometry data shows intra-day variabilities,which give evidence for stellar pulsations. Based on our analysis, the observedRV variations are most likely caused by the presence of unseen planetarycompanions. Assuming a primary mass of 0.83 M\odot, we computed minimumplanetary masses of 0.78 MJup for the inner and 2.93 MJup for the outer planet.The semi-major axes are a1 = 0.07 AU and a2 = 0.81 AU, respectively.Conclusions. HIP 11952 is one of very few stars with [Fe/H]< -1.0 which haveplanetary companions. This discovery is important to understand planetformation around metal-poor stars
