Mary O’Connell’s Bar, affectionately known as “Mary O’s,” is a deeply rooted, family-run pub in the heart of Ballincollig, County Cork, Ireland. Established by the O’Connell clan in 1924 (though the building is listed on deeds as a pub dating back to 1701), it has remained a central pillar of the local community for nearly a century, currently overseen by the Stevenson family. The establishment maintains a genuine and warm atmosphere, successfully blending its rich heritage with the needs of a modern village pub, reflecting a true community ethos where “everybody knew each other” from its early days as a local GAA hub.

The pub is renowned for its welcoming ambiance and diverse offerings, catering to a wide range of patrons throughout the day. In the morning, the lounge area is active with customers enjoying breakfast and coffee, while the main bar is popular for “morning time pints” and quiet social activities like crosswords and chess. Mary O’s features a strong emphasis on sports viewing across eight large-screen TVs, alongside a full menu of drinks that includes a generous draught selection and a recently added cocktail menu, ensuring it retains its status as a lively and essential Ballincollig institution.
