Abhurite is a mineral of tin, oxygen, hydrogen, and chlorine with the formula Sn₂₁O₆(OH)₁₄Cl₁₆ or Sn₃O(OH)₂Cl₂.Richard V. Gaines, H. Catherine W. Skinner, Eugene E. Foord, Brian Mason, and Abraham Rosenzweig: "Dana's new mineralogy", p. 401. John Wiley & Sons, 1997 It is named after its type locality, a shipwreck with tin ingots at Sharm Abhur, a cove near Jeddah in the Red Sea. Abhurite forms alongside other tin minerals like romarchite and cassiterite.{{Cite book|last1=Memet|first1=J.
