As in previous years, the Harrisburg St. Patrick's Day Parade's line of march is organized into four groups for ease of manageability. Each parade group is symbolically named after one of Ireland's four provinces; Leinster, Munster, Connacht and Ulster.

Those participating in the parade will be assigned a position within one of the four groups or "provinces" as well as an assembly location on the grounds of the Capitol Complex after a parade application is submitted.
