The invention discloses a foam magnesium oxychloride cementitious composite material for prefabricated partition wallboards and a preparation method of the foam magnesium oxychloride cementitious composite material. The foam magnesium oxychloride cementitious composite material is prepared from, by weight, 15-25 parts of magnesium chloride hexahydrate, 40-80 parts of water, 80-100 parts of light calcined magnesia, 5-40 parts of active filler, 1-10 parts of inert filler, 1-5 parts of a compound modifier and 10-40 parts of a compound foaming agent. The preparation method includes: preparing the magnesium chloride hexahydrate into a water solution, adding the light calcined magnesia and the active filler, and stirring for 1-5min; sequentially adding the compound modifier and fiber filler, and stirring for 5-25min; adding foam pre-prepared by the compound foaming agent, and stirring for 1-5min; injecting obtained foam magnesium oxychloride cementitious material slurry into moulds, and performing curing and formin
