Luthigh (also known as Luthig, Okara, Winduwinda, Uradhi, Teppathiggi or Ludhigh, pronounced ) is an extinct Paman language formerly spoken on the Cape York Peninsula of Queensland, Australia, by the Luthigh people. It is unknown when it became extinct. It constitutes a single language with Mpalitjanh. According to Sharp (1939), the neighboring Unjadi language differed only marginally from that spoken by the Okara [Luthigh].
