A Military Officers' Wives' Club (abbreviated MOWC) is a social club on many United States military installations, in which wives of military officers come together for social events. Aside from being a social organization, many MOWC organizations raise money to support charitable organizations in their local area.
Some clubs have changed their names to Military Officers' Spouses' Club (MOSC), in an effort to include both male and female members.
