Pimmit Hills is a census-designated place (CDP) in Fairfax County, Virginia. The population was 6,152 at the 2000 census. In practical terms, it is a neighborhood within a densely-populated urban area. It is estimated that there are approximately 1650 homes in Pimmit Hills.

It is found within the triangle made by the intersection of three highways: I-495 (the Capital Beltway), I-66, and Route 267 (the Dulles Toll Road). Within this triangle, the actual bounds of the neighborhood are Lemon Road Creek, State Route 7, and Magarity Road.

The houses in Pimmit Hills were mostly built during the late 1940s and early 1950s for World War II and Korean War veterans and their families. The houses are mostly single-family detached dwellings, with an average property size of 1/4 acre (1,000 m²). The neighborhood diverges from surrounding areas in that almost all houses are built using a very similar style. When the houses were first built, all trees in the area were removed. However, 50 years later the area is known for its population of large oaks, Tulip trees and other trees.

During the 1970s the area suffered from depressed real estate values and received a bad reputation as hosting poorly maintained properties. This began to turn around in the 1990s. Current real estate values mirror the rest of northern Virginia, with extreme value appreciation within the last several years.

Several attempts have been made by commercial developers to buy up Pimmit properties and convert them to higher-density housing such as condominiums or town houses, but so far these have been resisted by homeowners. Add-ons to the original houses such as second floors, basements, and same-floor expansions are common. Also, in recent years, many properties were purchased, demolished and replaced by brand new homes, (often mini-mansions).
