阿尔博因，（德语：Alboin，意大利语称为阿尔博因诺 Alboino；？~572年或573年）伦巴底人的领袖，意大利伦巴第王国的创建者。

阿尔博因在565年继承其父奥多因，成为居住在多瑙河与亚得里亚海之间的日耳曼蛮族伦巴底人的首领。568年，在来自亚洲的强大游牧民族阿瓦尔人的帮助下，阿尔博因领导自己的部落打败了另一支日耳曼部落格皮德人。阿尔博因杀害了格皮德人的首领坎尼蒙德，并且拿后者的头骨当杯子。

阿尔博因强迫坎尼蒙德的女儿罗莎蒙德成为他的配偶。他随即率领数万名伦巴底人和萨克森人翻越阿尔卑斯山，向意大利迁徙。他在569年攻占米兰，然后经过三年的苦战征服了帕维亚。阿尔博因最终征服了意大利南部，在波河河谷地带创建起伦巴第王国，定都于帕维亚。

Alboin (530s – June 28, 572) was king of the Lombards from about 560 until 572. During his reign the Lombards ended their migrations by settling in Italy, the northern part of which Alboin conquered between 569 and 572. He had a lasting effect on Italy and the Pannonian Basin; in the former his invasion marked the beginning of centuries of Lombard rule, and in the latter his defeat of the Gepids and his departure from Pannonia ended the dominance there of the Germanic peoples.
