Mount Blackburn (Ahtna: K’ats’i Tl’aadi) is the highest peak in the Wrangell Mountains of Alaska in the United States.

[3] The western of Blackburn's two summits is the mountain's highest point, a fact that was not understood until the 1960s when new USGS maps were published.

The first ascent of the west peak, and hence Mount Blackburn, was done on May 30, 1958, by Bruce Gilbert, Dick Wahlstrom, Hans Gmoser, Adolf Bitterlich, and Leon Blumer via the North (also called the Northwest) Ridge.

This team made the first ascent of Blackburn but did not even know it at the time due to the incorrect identification of the highest point.

"[4] Kennedy Peak, or East Blackburn, 16,286 ft (4,964 m), is the eastern summit and was originally thought to be the highest point.

The first ascent of this summit was made in 1912 by Dora Keen and George Handy via the Kennicott Glacier (on the south side of the mountain) and East Face.
