Twin Brothers is a 6,863-foot (2,092 m) Navajo Sandstone mountain in Zion National Park in Washington County, Utah, United States.

[4] Twin Brothers is situated one-half mile (0.80 km) immediately north of The East Temple, and one-half mile (0.80 km) immediately south of Mountain of the Sun, towering 2,800 feet (850 m) above the floor of Zion Canyon.

It is set on the east side of the North Fork of the Virgin River which drains precipitation runoff from this mountain.

Mount Spry, set southwest and below Twin Brothers, often appears in photos taken of both from park headquarters.

This desert climate receives less than 10 inches (250 millimeters) of annual rainfall, and snowfall is generally light during the winter.
