查莫罗人（西班牙文：Chamorro）是对马里亚纳群岛上土着人的称呼。其中最为人们所了解的是关岛查莫罗人。查莫罗人属于密克罗尼西亚人种，在民族学界对其起源存在较大争议，但一般认为查莫罗人在公元前2000年左右从东南亚迁徙到马里亚纳群岛，并在此定居下来。古代查莫罗人擅长远距离航海，同加罗林群岛存在贸易往来。17世纪后期，西班牙人在关岛创建殖民统治，引起查莫罗人的反抗。经过残酷的西班牙-查莫罗战争后，纯血种查莫罗人所剩无几。今天的查莫罗文化融合了西班牙、美国、菲律宾等各国文化，而古代查莫罗文化则在很大程度上已经消失殆尽。

The Chamorro people are the indigenous peoples of the Mariana Islands; politically divided between the United States territory of Guam and the United States Commonwealth of the Northern Mariana Islands in Micronesia. Today, significant Chamorro populations also exist in several U.S. states including Hawaii, California, Washington, Texas, Tennessee, Oregon, and Nevada. According to the 2000 Census, approximately 65,000 people of Chamorro ancestry live on Guam and another 19,000 live in the Northern Marianas. Another 93,000 live outside the Marianas in Hawaii and the West/Pacific coast of the United States. The Chamorros are primarily Austronesian.
