The Boston Citgo sign is a large, double-faced sign featuring the logo of the oil company Citgo that overlooks Kenmore Square in Boston. The sign was first built in 1940 and replaced with Citgo's present logo in 1965. The sign has become a landmark of Boston through its appearance in the background of Boston Red Sox games at Fenway Park. In 2016, the Boston Landmarks Commission granted preliminary landmark status to the sign to study whether the sign should receive historic preservation protection as a Boston Landmark.

The Citgo sign is a two-sided 60-foot (18 m) square white sign with the Citgo logo, called the trimark, and the word mark CITGO. The sign advertises the oil company Citgo, which is a subsidiary of Petróleos de Venezuela S.A. The sign features thousands of light-emitting diodes (LEDs) that turn off every night at midnight. The current sign was unveiled in March 2005 after a six-month restoration project. LEDs were selected for their durability, energy efficiency, intensity, and ease of maintenance. On October 15, 2008, a small electrical fire inside the sign caused approximately $5,000 worth of damage, partially melting the plastic and leaving visible smoke damage. The Citgo sign was shut down for several months beginning in July 2010 to replace the LEDs with a newer version hopefully more capable of withstanding the winds and temperature extremes that affect the sign. Earlier versions featured neon lighting; the pre-2005 sign contained 5,878 glass tubes with a total length of more than 5 miles (8.0 km). Service on the sign is provided by Federal Heath Sign Company.

The Citgo sign is known nationally for appearing above the Green Monster during televised games of the Boston Red Sox at Fenway Park. The sign has been nicknamed "See It Go," especially when a home run is hit during a game. This visibility has led to the installation of replica signs. Minute Maid Park, home of the Houston Astros, has a replica of the sign behind left field. Replicas of the sign also appear in two minor league baseball ballparks. Hadlock Field, home of the Double-A Portland Sea Dogs in Portland, Maine, has a replica of the Citgo sign above its replica of the Green Monster, the Maine Monster. The Double-A Astros affiliate Corpus Christi Hooks have a 50-foot (15 m) square replica of the sign at their ballpark, Whataburger Field. The association with Fenway Park and the Red Sox is so strong that some local Little League fields often are decorated with replicas of the Citgo sign. The sign was highlighted in the 1968 short film Go, Go Citgo, a 1983 Life Magazine photograph feature, and the 1989 feature film Field of Dreams. The sign is caricatured in Neal Stephenson's 1984 book The Big U as "the Big Wheel sign," which is worshipped by members of a fictional American Megaversity fraternity.
