Tarzan the Tiger (1929) is a Universal movie serial based on the novel Tarzan and the Jewels of Opar by Edgar Rice Burroughs. It stars Frank Merrill as Tarzan, Natalie Kingston as Jane, and Al Ferguson. It was directed by Henry MacRae.

It was once considered a lost film, but a copy has since been found. Today the serial is available on DVD and, in the public domain, available for download on the internet.

Lord Greystoke (Tarzan) returns to Africa, with Lady Jane and friend Albert Werper, in order to return to Opar. He needs the treasure of Opar in order to secure his estates in England. Werper, however, is actually interested in the gold itself. He is in league with Arab slave trader Achmet Zek, who wishes revenge on Tarzan and Lady Jane for himself.

Frank Merrill reprised his role as Tarzan from Tarzan the Mighty. His performances in these two serials make him the last silent Tarzan and the first sound Tarzan. Merrill did his own stunts and devised the original Tarzan yell.

Natalie Kingston was again cast as the love interest but this time played the traditional character of Lady Jane instead of Mary Trevor (from Tarzan the Mighty). The change was not explained in the serial.

Al Ferguson was also again cast as the villain of the story, but not as the same character (or even a slightly renamed character, as with Jane. In Tarzan the Mighty he played the pirate Black John).

Mademoiselle Kithnou was a dancer and actress of mixed Indian and European descent from Puducherry, at that time in French India, or possibly from Mauritius.
