A Line in the Sand is a two-part British television mini-series, adapted by Gerald Seymour from his 1999 novel of the same name, that first broadcast on ITV on 7 June 2004. The series, directed by James Hawes, stars Ross Kemp as Frank Parry, a former MI6 spy who tries to escape his past by hiding out in a remote village on the Suffolk coast. The series was originally scheduled for broadcast in September 2001, but was later shelved until June 2004, due to a major plotline which involved Middle-Eastern terrorists, which was deemed to be too sensitive following the 9/11 terror attacks in the United States earlier that month.

For some international broadcasts, the series was broadcast as one feature-length film. In the United States, the series aired two years prior to the UK premiere, airing on 18 June 2002. The series was released on DVD via ITV Studios on 15 January 2007. The series is notable for featuring a very early role for Danny Mac, before his casting as Dodger Savage in Hollyoaks.
