Lyon Park is served by three neighborhood organizations working together.

1. The Lyon Park Citizens Association is a nonprofit, non-partisan organization established to promote the welfare and advancement of the Lyon Park community in particular and Arlington County in general. The Association seeks to represent the interests of the Lyon Park community at public hearings and meetings and to distribute information on issues of concern to the community. The Lyon Park Citizens Association meets at the Lyon Park Community House, 414 N. Fillmore Street, at 7:30 PM on the second Wednesday of each month, except during July and August.
   
   
2. The Board of Governors of the Lyon Park Community Center. The Lyon Park community owns Lyon Park and is responsible for the upkeep of the grounds and the historic Community House building, a responsibility exercised through the Community Center Board of Governors. The volunteer board is comprised of five members from the Lyon Park Civic Association and five members from the Lyon Park Woman’s Club. Funds for maintaining the Park and Community Center are derived through various community activities and rental of the Community House, as well as donations from individuals, the Citizens Association and the Woman’s Club. The Lyon Park Community Center is a registered Section 501c(3) charitable organization, and donations to it are generally tax-deductible. The Board of Governor’s of the Lyon Park Community Center is the sponsor for most of the monthly community events conducted at the Park.
   
   
3. The Lyon Park Woman’s Club was established in 1925 and historically functioned like a traditional woman’s club, supporting various charities. Currently, its members enjoy each other’s company and engage in activities that support the Lyon Park Community Center, sponsoring several community events. Although its name implies the group is for women, everyone is welcome. And some members live outside Lyon Park, making the Woman’s Club a way for nonresidents who have an interest in the Community Center and Park to get involved. Pot-luck lunch meetings are scheduled on the 3rd Thursday of each month at noon, from September to May, at the Lyon Park Community Center.
