Seven Fingered Jack is a mountain in the North Cascades in the U.S. state of Washington.

It is located at the north end of the Entiat Mountains, a sub-range of the Cascade Range.

[5] Together they form a high, curved ridge from which the headwaters of the Entiat River flow eastward.

Thus Seven Fingered Jack sits on the boundary between the drainage basins of the Entiat and Wenatchee rivers.

[6] Seven Fingered Jack was once called the Entiat Needles, after their distinctive craggy granite summits.
