Seven Sisters Peaks is a 2,747-metre (9,012-foot) multi-summit massif located in the Bulkley Ranges of the Interior Mountains in British Columbia, Canada. The massif is situated within Seven Sisters Provincial Park and Protected Area, 10 km (6 mi) southeast of Cedarvale, south of Orion Peak, and surrounded by Seven Sisters Glacier. The highest peak of the seven is called Weeskinisht Peak. Precipitation runoff from the mountain and meltwater from the glacier drains into tributaries of the Skeena River. The nearest higher peak is Howson Peak, 68.8 km (43 mi) to the south-southeast. Based on the Köppen climate classification, Seven Sisters Peaks is located in a subarctic climate zone with cold, snowy winters, and mild summers. Temperatures can drop below −20 °C with wind chill factors below −30 °C. Seven Sisters Mountain was the name adopted in 1948, but the mountain's name was changed and officially adopted October 4, 1951, by the Geographical Names Board of Canada.

The individually named peaks of the massif from west to east are Tlooki Peak, Weeskinisht Peak, Tagai Peak, Tingi Peak, Kitshin Peak, Kletoosho Peak, and Tuatoosho Peak, which are the Tsimshian/Gitxsan words for One, "Top of the Mountain", Three, Four, Five, Six, and Seven, respectively. With the exception of Weeskinisht, the other names were submitted by Neal M. Carter of the Alpine Club of Canada and officially adopted in 1977.
