The divide between the different neighborhoods of Los Angeles can feel like one between cities, and in some cases—like West Hollywood, Santa Monica, Beverly Hills, and Culver City—it literally is.

L.A. is a big place—the Los Angeles TimesMapping L.A. project has 272 neighborhoods in the city. Outlining the origin of all their names would be a project worthy of a large research university. In order to make this both manageable and comprehensible, I stuck to the neighborhoods and cities within a few areas of the Times’ map: the Westside, South L.A., Central L.A., Southeast, Eastside, and Northeast L.A. This leaves out the many valleys and mountains and bays that make Los Angeles County so sprawling, but it also hits most of the places you’d think of as
