光谱分析是根据物质的光谱来鉴别物质和确定其化学组成。

使用光譜儀分光光度計與相關電子設備,量測不同發射光源之光譜譜線。並採用儀器所提供之固定光源,量測不同物質之吸收光譜、穿透光譜與反射光譜。 因为不同元素的光谱会有不同的位置的颜色的谱线,或者会缺少某些谱线,但含有相同元素的物质的谱线却总是会在同一个位置具有相同颜色的谱线。光谱分析就是利用这个原理来分析物质的元素组成的。

光譜分析在科學史中有一定地位。無論在物理、化學、天文學、生物、醫學、生化、化工等領域,都有重要的影響、發現和應用。

光譜分析可利用光譜儀以及圖像軟體進行處理以獲取物質的化學組成。同時配合試算表進行數據分析。

天文学裡通过光谱分析来对恒星小行星进行分类(詳見:恆星光譜分類小行星光譜分類)。
