The invention discloses a method for producing monascus pigment from monascus fermented shrimp head and shell. The method comprises the following steps: performing slant seed culture, liquid seed culture and fermentation culture of monascus, wherein shrimp shell powder is added during the liquid seed culture and fermentation culture. Through the monascus pigment production method disclosed by the invention, the prepared monascus pigment has the advantages that the yield is high, and the color value of the monascus pigment is up to 49.75U/ml; and moreover, the waste shrimp shell powder can be utilized, and the fermentation cost is lowered.
