Territorio y organización thumb|derecha|Basílica de San José, en Webster
La diócesis tiene 3966 km² y extiende su jurisdicción sobre los fieles católicos de rito latino residentes en el condado de Worcester en el estado de Massachusetts.
La sede de la diócesis se encuentra en la ciudad de Worcester, en donde se halla la Catedral de San Pablo. En Webster se encuentra la basílica menor de San José.
En 2023 en la diócesis existían 91 parroquias.
En 2004, el obispo Reilly agrupó las parroquias en "aglomeraciones".https://web.archive.org/web/20070928100142/http://www.worcesterdiocese.org/bishopsoffice/Pastoral_Planning/Cluster%201Cluster%20%202.pdf El propósito de este sistema es permitir que las comunidades se reúnan para un evento regional. Además, los sacerdotes pueden sustituirse entre sí en una parroquia en particular.
