Here we report the positive muon spin relaxation ($\\mu^+$SR) study of polycrystalline La$_3$Ni$_2$O$_{6.92}$ under ambient pressure. Zero-field $\\mu^+$SR experiments reveal the existence of magnetic order in La$_3$Ni$_2$O$_{6.92}$ with $T_{N}=154\\ \\rm{K}$. The weak transverse field $\\mu^+$SR measurements confirms the bulk nature of magnetism.
