Richard de Clare, 2nd Earl of Pembroke (of the first creation), Lord of Leinster, Justiciar of Ireland (1130 – 20 April 1176), also known as Richard FitzGilbert, was an Anglo-Norman nobleman notable for his leading role in the Anglo-Norman invasion of Ireland. Like his father, Richard fitz Gilbert has since become commonly known by his nickname Strongbow (Norman French: Arc-Fort), which may be a mistranscription or mistranslation of "Striguil".

His son Gilbert de Striguil (or de Strigoil) died unmarried before 1189 and the earldom passed via Richard's daughter Isabel to her spouse William Marshall.
