巴纳姆峰是南极洲的山峰，位于罗斯属地，海拔高度2,940米，处于拉韦涅冰川口以南，该山峰在1929年11月由美国海军少将发现，以《标准邮报》（Syracuse Post-Standard）发行人命名。

Barnum Peak (85°23′S 171°40′W / 85.383°S 171.667°W / -85.383; -171.667) is a peak, 2,940 metres (9,650 ft) high, surmounting the east end of a prominent snow-covered rock divide near the head of Liv Glacier, just south of the mouth of LaVergne Glacier. It was discovered by Rear Admiral Byrd on the Byrd Antarctic Expedition flight to the South Pole in November 1929, and named by him for J.D. Barnum, publisher of the Syracuse Post-Standard and contributor to the expedition.
