The Solid Gold Cadillac is a 1956 American comedy film directed by Richard Quine and written by Abe Burrows, Howard Teichmann, and George S. Kaufman.

At a shareholders meeting for International Projects, a billion-dollar corporation, John T. Blessington announces that he is replacing Edward L. McKeever, the company's founder, president and chairman of the board who is resigning to serve as Secretary of Defense in Washington D.C. Laura Partridge, a stockholder with just ten shares, infuriates the company's arrogant, self-serving executives by repeatedly exercising her right to ask questions during the meeting.

Blessington devises a plan to hire Laura for the meaningless position of director of shareholder relations in order to keep her occupied and out of the executives' business.

However, Laura discovers that Blessington's unqualified brother-in-law Harry Harkness has driven an apparent competitor into bankruptcy, unaware that International Projects actually owns the smaller company.

She agrees to go, but secretly intends to convince McKeever to return and retake control from the crooked board even though, when assuming his Cabinet position, he had sold his shares in the company to avoid any conflict of interest.

For its final scene, the film changes from black-and-white to color, showing the small stockholders' wedding gift to Laura, a gleaming solid gold Cadillac that she drives around Manhattan.
