Phone Booth is a 2003 American suspense/psychological thriller film about a man who is held hostage in a telephone booth by a sniper. It stars Colin Farrell, Kiefer Sutherland, Forest Whitaker, Katie Holmes, and Radha Mitchell. The film was directed by Joel Schumacher, with music composed by Harry Gregson-Williams. The film was originally scheduled to be released on November 15, 2002, but was delayed until April 4, 2003 due to the Beltway sniper attacks.

Stu Shepard (Colin Farrell) is an arrogant publicist who has been seeing Pam (Katie Holmes) despite his marriage to Kelly (Radha Mitchell). He uses one of New York City's last remaining public phone booths to contact Pam. During the call, he is interrupted by a pizza delivery man, attempting to give him a free pizza, but Stu ignores him. As soon as he completes his call to Pam, the phone rings again; Stu answers to find that the caller (Keifer Sutherland) warns him not to leave the booth, and that he will say hello to Kelly for him, leaving Stu panicked about the situation.

A telephone booth, telephone kiosk, telephone call box or telephone box is a small structure furnished with a payphone and designed for a telephone user's convenience. In the USA and Canada, "telephone booth" is used, while in the United Kingdom, Australia and the rest of the Commonwealth of Nations it is a "telephone box" or "phone box". Such a booth usually has a door to provide privacy and a window to let others know if the booth is in use. The booth may be furnished with a printed directory of local telephone numbers, and a booth in a formal setting, such as a hotel, may be furnished with paper and pen and even a seat. An outdoor booth may be made of metal and plastic to withstand the elements and heavy use, while an indoor booth (once known as a silence cabinet) may have more elaborate architecture and furnishings. Most outdoor booths feature the name and logo of the telephone service provider.

Starting in the 1970s pay telephones were less and less commonly placed in booths in the United States. In many areas where they were once common, telephone booths have now been almost completely replaced by non-enclosed pay phones. In the United States, this replacement was caused, at least in part, by an attempt to make the pay telephones more accessible to disabled people. However, in the United Kingdom, telephones remained in booths more often than the non-enclosed set up. Although still fairly common, the number of phone boxes has declined sharply in Britain since the late 1990s due to the boom of mobile phones.
