We present an investigation on the large magnetic anisotropy of Fe_{2}P, based on {\it Ab Initio} density-functional theory calculations, with a full potential linear muffin-tin orbital (FP-LMTO) basis. We obtain an uniaxial magnetic anisotropy energy (MAE) of 720 \mueV/f.u., based on a band structure analysis the microscopical origin of such a large magnetic anisotropy is explained. We also show tahta by straining the crystal structure, the MAE can be enhanced further.
