Lead picrate, Pb(C₆H₂(NO₂)₃O)₂, is an organic chemical compound from the group of picrates, salt of picric acid and lead with a +2 oxidation state. It is an initiating explosive, and thus highly sensitive.^[1]

For demonstration purposes, it can be most easily and safely prepared in situ. Picric acid is mixed with red lead (Pb₃O₄), and then heated. It is not recommended that more than 50 mg is ever made at any one time. At around 130–160 °C, as the picric acid melts, the mixture detonates violently.
