Tanner '88 is a political mockumentary miniseries written by Garry Trudeau and directed by Robert Altman. First broadcast by HBO during the months leading up to the 1988 U.S. presidential election, it purports to tell the behind-the-scenes story of the campaign of fictitious former Michigan U.S. Representative Jack Tanner, played by Michael Murphy, during his bid to secure the Democratic Party's nomination for president of the United States.

The story is told from a number of different points of view, including Tanner, his campaign staff, the small army of news reporters that constantly follow the candidate, and volunteers. Many political figures of the time appear (some in cameos, some extended), including Bruce Babbitt, Bob Dole, Kitty Dukakis, Gary Hart, Jesse Jackson, and Pat Robertson. Trudeau and Altman revisited the story 16 years later in Tanner on Tanner.
