Disclosed is a preparation method for an organic silver colloid, comprising: dissolving an inorganic silver salt solid in water to obtain a silver precursor solution; diluting an organic complexing agent by water to obtain an organic complexing solution; dissolving a stabilizer in water to obtain a stabilizer solution; and mixing the stabilizer solution, the organic complexing solution and the silver precursor solution, and performing a complexation reaction to obtain the organic silver colloid. Further disclosed in the present application is an organic silver colloid, comprising organic silver colloid particles and a stabilizer. In the organic silver colloid, the silver content is 0.01-0.2 mol/L, preferably 0.01-0.05 mol/L. The organic silver colloid prepared by the method of the present application is high in stability, stable and uniform in colloid color, stable and uniform in viscosity, and free of viscosity difference between the upper liquid level and the lower liquid level.
