Dark Rainbow is the fifth studio album by British rock band Frank Carter and the Rattlesnakes, released on 26 January 2024 through International Death Cult and AWAL.

[1] Mojo stated that "After the initial shock, the pair's songwriting smarts cuts through persuasively, alongside strong messaging about acknowledging your needs and vulnerabilities".

[4] Jack Terry of DIY felt that the album "sounds like many of the best bits of each of their previous records" and also wrote that "the eleven tracks here are perhaps their most consistent and level to date [...] it seems they're keeping themselves well oiled".

's Mark Sutherland stated that it is "the sheer quality of the songs that is the most seductive thing here" as it is "augmented with pianos, synths and strings, heavy with mature power ballads and emotionally charged throughout".

[5] Simon K. of Sputnikmusic called it "easily the best Rattlesnakes album since Modern Ruin" with "sashaying, fuzzed-out rock grooves, retro-esque synths, dour ballads, and a creeping psychedelic undercurrent [being] the main order of the day, and while the guitar aspect of the record certainly has the most derivative aspects, it's all pulled off pretty well".
