Navajo weaving (Navajo: diyogí) are textiles produced by Navajo people, who are based near the Four Corners area of the United States. Navajo textiles are highly regarded and have been sought after as trade items for more than 150 years. Commercial production of handwoven blankets and rugs has been an important element of the Navajo economy. As one art historian wrote, "Classic Navajo serapes at their finest equal the delicacy and sophistication of any pre-mechanical loom-woven textile in the world."

Navajo textiles were originally utilitarian weavings, including cloaks, dresses, saddle blankets, and similar items. By the mid-19th century, Navajo wearing blankets were trade items prized by Indigenous peoples of the Great Plains and neighboring tribes. Toward the end of the 19th century, Navajo weavers began to make rugs for non-Native tourists and for export.

Earlier Navajo textiles have strong geometric patterns. They are a flat tapestry-woven textile produced in a fashion similar to kilims of Eastern Europe and Western Asia, but with some notable differences. In Navajo weaving, the slit weave technique common in kilims is not used, and the warp is one continuous length of yarn, not extending beyond the weaving as fringe. Traders from the late 19th and early 20th century encouraged adoption of some kilim motifs into Navajo designs. Textiles with representational imagery are called pictorial. Today, Navajo weavers work in a wide range of styles from geometric abstraction and representationalism to biomorphic abstraction and use a range of natural undyed sheep wool, natural dyes, and commercial dyes.
