In this paper, we present the results from a  Suzaku  observation of the Galactic supernova remnant G272.2−3.2. The spectra of G272.2−3.2 are well fitted by a single‐temperature variable abundance non‐equilibrium ionization (VNEI) model with an electron temperature  kT  e ∼ 0.77 keV, an ionization time‐scale τ∼ 6.5 × 10 10  cm −3  s and an absorbing column density  N  H ∼ 1.1 × 10 22  cm −2 . We have detected enhanced abundances of Si, S, Ca, Fe and Ni in the centre region, indicating that the X‐ray emission has an ejecta origin. We estimate that the electron density is  n  e ∼ 0.48 f  −1/2  cm −3 , the age is ∼4300 f  1/2  yr and the X‐ray total mass is  M  x = 475 f  1/2  M ⊙  by taking the distance to be  d = 10 kpc. To understand the origin of the centrally peaked X‐ray emission of the remnant, we have studied the radial variations of the electron temperature and surface brightness. The relative abundances in the centre region suggest that G272.2−3.2 is the result of a Type Ia supernova explosion.
