蘇西與女妖（英語：Siouxsie and the Banshees，/ˈsuzi ænd ðə ˈbænʃiz/，SU-zi-and-the-BAN-shees）是一支於1976年由主唱蘇西蘇（英语：Siouxsie Sioux）和貝斯手史蒂芬·塞維林（英语：Steven Severin）在倫敦成立的英國搖滾樂團。樂團在同輩以及後來的音樂家們之間有著廣泛的影響，《泰晤士报》更稱他們為「後龐克時代最大膽、最不妥協的音樂冒險家之一」。[1]
樂團最初從龐克音樂出發，加上吉他手約翰·麥凱（英语：John McKay (musician)）和鼓手肯尼·莫里斯（英语：Kenny Morris (musician)）來創造出一種「充滿大膽節奏和聲音實驗的不和諧後龐克風格」。[1]樂團1978年的首張專輯《尖叫（英语：The Scream (album)）》得到評論的青睞。
他们已被视为1970年代最有影响力的摇滚乐队之一[2][3][4][5][6][7][8][9][10]。
...with the Banshees she helped to invent a form of post-punk discord full of daring rhythmic and sonic experimentation... The Banshees stand proudly alongside PIL, Gang of Four and the Fall as the most audacious and uncompromising musical adventurers of the post-punk era.
Siouxsie and the Banshees were one of our big influences [...] The Banshees first LP was one of my favourite ever records, the way the guitarist and the drummer played was a really unusual way of playing

It would be Siouxsie and the Banshees to whom I most felt some kind of affinity. [...] the bass-led rhythm, the way first drummer Kenny Morris played mostly toms. [...] The banshees had that [...] foreboding sound, sketching out the future from the dark of the past. [...] hearing the sessions they'd done on John Peel's show and reading gigs write-ups, [...] they sounded interesting.
a massive influence on me [...] They were the group who led me towards doing Pornography. They drew something out of me.

I think the final straw came when I played Michael the demos for the next album and he hated them. He wanted us to be XTC part 2 and – if anything – I wanted us to be the Banshees part 2.
I played with the Banshees through our first tour [1979], and it allowed me to think beyond what we were doing. I wanted to have a band that does what Steve Severin and Budgie do, where they just get a bassline and the drum part and Siouxsie wails.

Colin Greenwood remembers: "The first single we're releasing is actually the longest song on the record. ("There There"). It was all recorded live in Oxford. We all got excited at the end because Nigel was trying to get Jonny to play like John McGeoch in Siouxsie and the Banshees. All the old farts in the band were in seventh heaven.
The band that really changed my life was R.E.M. and Siouxsie and the Banshees...". "My favourite show I ever saw then was Siouxsie and she was absolutely amazing. ... She's totally in command of the whole audience.
Q: Was there any figure who connected with you when you were just a listener? A: It's hard to beat Siouxsie Sioux, in terms of live performance. She is so exciting to watch, so full of energy and human raw quality.
