A desirable nabe in New Haven, Connecticut, filled with historic homes and located just west of Edgewood park. The neighborhood is home to shops, fancy hair salons and brunch places, a bunch of synagogues, art fairs, a dozen or so galleries, a year-round farmer's market, and a few of the city's better performing elementary schools.

Many if not most of New Haven's political leaders live in Westville. The area is primarily Jewish and Catholic.

The neighborhood varies somewhat. Most of it consists of gorgeous, expensive houses built around World War One and which are filled with a diverse group of upper-income, highly educated people (about half affiliated with Yale). A few small sections near Valley Street and Whalley Avenue are lower income areas. The nabe borders West Rock which is a prominent geological feature, home to the West River, and a nice park for walking or hiking.

Not to be confused with Upper Westville or Amity, out towards Woodbridge, which are typical working class suburban districts with smaller post war homes.

Westville is sometimes compared to the city's East Rock neighborhood, but consists more of expensive single family homes whereas East Rock is primarily multi family homes and condos.
