The Worcester Worcesters were a 19th-century Major League Baseball team from 1880 to 1882 in the National League. The team is referred to, at times, as the Brown Stockings or the Ruby Legs; however, no contemporary sources from the time exist that support the use of either name. The team played their home games at the Worcester Driving Park Grounds in the Worcester Agricultural Fairgrounds, located south of Highland Street between Sever Street and Russell Street in Worcester, Massachusetts.

The National League of Professional Baseball Clubs, known simply as the National League (NL), is the older of two leagues constituting Major League Baseball (MLB) in the United States and Canada, and the world's oldest extant professional team sports league. Founded on February 2, 1876, to replace the National Association of Professional Base Ball Players (NAPBBP) of 1871–1875, the NL is sometimes called the Senior Circuit, in contrast to MLB's other league, the American League, which was founded 25 years later and is called the "Junior Circuit". Both leagues currently have 15 teams.
