Lalo Schifrin (born June 21, 1932) is an Argentine composer, pianist and conductor. He is best known for his film and TV scores, such as the Mission: Impossible theme. He has received four Grammy Awards and six Oscar nominations.

One of Schifrin's most recognizable and enduring compositions is the theme music for the long-running TV series Mission: Impossible. It is a famously distinctive tune written in an uncommon 5/4 time signature.
In 1970, he composed the Paramount Television (which by then had taken over production of Mission: Impossible) logo jingle "Color I.D." It was an 8-note jingle featuring horns, woodwinds and timpani. This music would have a long run in Paramount's TV production logos through 1987.

Schifrin's "Tar Sequence" from his Cool Hand Luke score (also written in 5/4) was the longtime theme for the Eyewitness News broadcasts on New York station WABC-TV and other ABC affiliates, as well as National Nine News in Australia. CBS Television used part of the theme of his St. Ives soundtrack for its golf broadcasts in the 1970s and early 1980s.
Schifrin's score for Coogan's Bluff in 1968 was the beginning of a long association with Clint Eastwood. Schifrin's strong jazz blues riffs were evident in Dirty Harry and, although similar to Bullitt and Coogan's Bluff, the score for Dirty Harry stood out for the sheer fear it generated when released.
Schifrin's working score for 1973's The Exorcist was rejected by the film's director William Friedkin. Schifrin had written six minutes of difficult and heavy music for the initial film trailer but audiences were reportedly too scared by the combination of sights and sounds. Warner Bros. executives told Friedkin to instruct Schifrin to tone it down with softer music, but Friedkin did not relay the message. Schifrin's final score was thrown out into the parking lot. Schifrin reported in an interview that working with Friedkin was the one of the most unpleasant experiences in his life.

In the 1998 film Tango, Schifrin returned to the tango music he had grown familiar with while working as Astor Piazzolla's pianist in the mid-1950s. He brought traditional tango songs to the film as well as introducing compositions of his own in which tango is fused with jazz elements.

In 1997, Aleph Records was founded by the composer.

He also wrote the songs for Splinter Cell: Pandora Tomorrow.
