Butler is an agrarian, unincorporated community in Baltimore County, Maryland. It is bordered to the west by Glyndon, east by Sparks, south by Cockeysville, and north by Upperco. It is often referred to as "Worthington Valley". For almost a century it has served as home to many equestrian events including the Grand Nationals and the Hunt Cup.
The history of the town is unknown. However, it has served as home to many of the states oldest and wealthiest families for at least 150 years. Butler also serves as home to two very historic churches. St. John's Episcopal Church serves as the burial place for many of Maryland's politicians from the late 18th, 19th, and early 20th centuries. Also, Black Rock Primitive Baptist Church is the site of the historic "Black Rock Address" which occurred on September 28, 1832.
