Duboce Triangle takes its name from Victor Duboce, a lieutenant colonel of the First California Volunteer Infantry who served in the Philippines during the Spanish–American War, and from the triangular shape formed by the intersection of Market, Castro, and Duboce Streets. The neighborhood's oldest surviving house at 22 Beaver Street dates to 1876, and a large Victorian apartment building on the north side of 400 Duboce Avenue — described as the largest wooden structure west of the Mississippi River to survive the 1906 earthquake — anchors its architectural heritage. The neighborhood was formerly known as Gaffney's Triangle, after a local politician, until the Federal Area Code Experiment (FACE) Program designated the census tract in the early 1970s and the Duboce Triangle Neighborhood Association (DTNA) was formed in 1975 under its first president, John Sanger.

The N Judah streetcar line runs through the heart of Duboce Triangle, and the neighborhood sits at the convergence of the N, J, K, L, and M Muni Metro lines — making it one of the most transit-connected corners of San Francisco. Market Street Railway operated more than one thousand streetcars through the corridor from 1921 to 1944, and the Duboce Avenue right-of-way served as an outdoor maintenance yard for the historic transit fleet. Duboce Park, the neighborhood's central green space, remains one of the city's most active community gathering spots.

The layered transit history and Victorian character of Duboce Triangle are exactly the kind of San Francisco story MY-NHD apparel puts on the map.
