爱尔兰英语（英语：Hiberno English 或 Irish English），是在爱尔兰使用的一种英语方言。

在诺曼入侵后的十二世纪晚期，英语第一次被带到了爱尔兰岛，开始英语只在都柏林附近的The Pale使用。都铎王朝期间，爱尔兰人夺回了被殖民者占有的土地。但是在都铎征服爱尔兰后，尤其是在圈地运动期间，英语得到大范围的扩张。至19世纪中期，英语成了爱尔兰的主要语言并延续至今，并且爱尔兰岛上残存的爱尔兰语也在受到英语很深的影响。 当代的爱尔兰英语受到爱尔兰语的强烈影响，这些影响体现在词汇语法发音和句子结构上。

Hiberno‐English (from Latin Hibernia: "Ireland") or Irish English refers to the set of English dialects natively written and spoken in Ireland.

English was brought to Ireland as a result of the Norman invasion of Ireland of the late 12th century. Initially, it was mainly spoken in an area known as the Pale around Dublin, with mostly Irish spoken throughout the rest of the country. By the Tudor period, Irish culture and language had regained most of the territory lost to the colonists: even in the Pale, "all the common folk… for the most part are of Irish birth, Irish habit, and of Irish language". However, the English conquest and colonisation of Ireland in the 16th century marked a revival in the use of English. By the mid-19th century, English was the majority language spoken in the country. It has retained this status to the present day, with even those whose first language is Irish being fluent in English as well.
