Ang fluor o plurina (Ingles: fluorine) ay isang elementong kimikal sa talahanayang peryodiko na sinasagisag ng simbolong F at nagtataglay ng atomikong bilang 9.

May atomikong timbang na 18.9984, punto ng pagyeyelong (FP) 62 °C, punto ng pagkulong 188.14 °C, espesipikong grabidad na 1.108 [sa anyong likido], at balensiyang 1) ay isang elementong haloheno. Isa itong elementong may kulay na maputlang dilaw. Bilang lason, mabagsik ito, nakakaagnas at nasa anyo ng isang gas. Ito ang pinaka-elektronegatibo at pinaka-reaktibo sa lahat ng mga elemento, at ginagamit na sangkap sa paggawa ng maraming uri ng mahahalagang mga kompawnd. Natuklasan ito ni Ferdinand Frederick Henri Moissan noong 1886.[16]
