Seosamh Laoide (English: Joseph H. Lloyd, 1865–1939), known as "Mac Tíre na Páirce" ("Wolf of the Park"), was an Irish language scholar and activist during the period 1893 – 1915. Today he is perhaps best remembered for his work on Irish placenames, particularly on the placenames of Dublin which often became the established Irish versions on the city's streets following the establishment of the Irish state in December 1922.
