Fatar jiki ce ta jiki, a cikin dabbobi da mutane. Yana rufe wajen jiki. A matsayin harsashi, yana kare mu daga raunuka da kwayoyin cuta. Yana da nauyi fiye da kowace gabo. A cikin babban mutum, girmansa ya kai kusan murabba'in mita biyu.
Fatar mu tana da siraran fata na waje, wanda kuma ake kira Horny Layer ko epidermis. Ya ƙunshi matattun ƙwayoyin cuta. A ƙarƙashinsa akwai fatar fata, dermis. A cikin dermis akwai jijiyoyi da tasoshin jini. Tushen gashi da gland na gumi da kuma magudanar ruwa ma suna can. Sebum yana tabbatar da cewa fata ba ta bushe ba.
A cikin fata akwai ƙananan rini da ake kira pigments? Mutane masu launin fata suna da launi mai yawa. Lokacin da rana ta haskaka fata, takan ƙara launi. Wannan yana sa fata ta yi duhu kuma ta fi kariya daga rana. Masu fatar jiki kuwa, suna samun konewar rana cikin sauki. Wasu mutane da dabbobi ba su da launi kwata-kwata. Ana kiranta albinism.
