氮磷族氧化物(oxypnictide)，是指具有氮族元素(第5族元素，即氮、磷、砷、锑及铋)、氧以及其他元素的化合物。

稀土过渡金属氮磷族化合物(rare-earth transition-metal oxypnictide, ReTmPnO)，如ReFePO、ReRuPO，及ReCoPO，具有锆铜硅砷型(ZrCuSiAs-type)的结构(常温下，空间群为P4/nmm) 。

In chemistry, oxypnictides are a class of materials including oxygen, a pnictogen (group-V, especially phosphorus and arsenic) and one or more other elements. Although this group of compounds has been recognized since 1995, interest in these compounds increased dramatically after the publication of the superconducting properties of LaOFeP and LaOFeAs which were discovered in 2006 and 2008. In these experiments the oxide was partly replaced by fluoride.
