The Amazing Quest of Ernest Bliss is a 1936 British romantic comedy film directed by Alfred Zeisler and starring Cary Grant. It is a remake of the 1920 film The Amazing Quest of Mr. Ernest Bliss, based on The Curious Quest, a 1919 novel by E. Phillips Oppenheim.

The film was issued in the United States in 1937 under the title The Amazing Adventure (and subsequently Romance and Riches), but edited down to 62 minutes from the reputed original UK running time of 80 minutes. All currently circulating copies are of the US edit, but the British Film Institute has several archive prints of 77 minutes in length. The film is in the public domain and appears on many budget VHS and DVD releases. As a non-US film that was not under copyright in its country of origin on 1 January 1996, it was not eligible for GATT.
