硝酸铅，IUPAC中文名称为硝酸铅(II)，是铅的硝酸盐，通常呈无色晶体或白色的粉末。与其它二价铅盐不同，硝酸铅溶于水。大家通常把金属铅或氧化铅与硝酸反应制得硝酸铅，再进一步合成其它铅化合物。

在历史上，硝酸铅是从中世纪以Plumb dulcis的名字为人们所认识的，那时从金属铅或氧化铅通过硝酸制备硝酸铅的生产都是小规模的。到19世纪时硝酸铅在欧洲和美国就被商业化生产，当时主要是用做制造颜料的主要原料，但是因为有毒，所以逐渐被毒性较低的二氧化钛取代。其它工业用途是作为热稳定剂在尼龙、聚酯和热成像纸涂料中使用。大约自2000年左右，硝酸铅已开始被用于氰化物炼金法。

Lead(II) nitrate is an inorganic compound with the chemical formula Pb(NO₃)₂. It commonly occurs as a colourless crystal or white powder and, unlike most other lead(II) salts, is soluble in water.

Known since the Middle Ages by the name plumb dulcis, the production of lead(II) nitrate from either metallic lead or lead oxide in nitric acid was small-scale, for direct use in making other lead compounds. In the 19th century lead(II) nitrate began to be produced commercially in Europe and the United States. Historically, the main use was as a raw material in the production of pigments for lead paints, but such paints have been superseded by less toxic paints based on titanium dioxide. Other industrial uses included heat stabilization in nylon and polyesters, and in coatings of photothermographic paper. Since around the year 2000, lead(II) nitrate has begun to be used in gold cyanidation.
