Christine L. T. Finn (1929 – 5 December 2007) was an English actress, known primarily for her role in the 1950s TV serial Quatermass and the Pit, and, after that, her voice work for the 1960s Thunderbirds television series.

She moved to Britain in July 1946 aboard the Cunard ship RMS Scythia from Bombay, just before the end of British rule, and found a clerical job with the BBC.

After joining the Birmingham Repertory Theatre, she remained in the company of actors for two years, departing with the role Lady Grey in Henry VI Part III at the Old Vic.

Soon afterwards, the director, Rudolph Cartier, cast her in the leading female role, Barbara Judd, in the science-fiction horror serial Quatermass and the Pit (1958–59).

In a book about his work, written by Andy Murray, Kneale recalled: "I'd liked Christine very much ... but she wasn't the kind of screen star that Hammer wanted.
