Thapsic acid (hexadecanedioic acid) is a naturally occurring dicarboxylic acid with the formula C₁₆H₃₀O₄.^[1] The name is derived from Thapsia, the Latin name for a Mediterranean perennial whose roots contain thapsic acid.

It has a role as a human metabolite.^[2] It is the conjugate acid of hexadecanedioate.
