Tommy Windich (c. 1840 – c. 20 February 1876) was an Indigenous Australian member of a number of exploring expeditions in Western Australia in the 1860s and 1870s. Tommy Windich (or Windiitj) was born around 1840 near in Western Australia. Little is known of his youth, but his skills in tracking and knowledge of a number of Aboriginal languages suggest a traditional upbringing, whereas his skills in horseriding and marksmanship indicate extensive contact with colonial culture. Windich and Cowits joined Constable Edwards in the police expedition east in May 1866 which discovered petroleum.
