Diamond Jubilee is the seventh studio album by Canadian band Cindy Lee, the project of musician Patrick Flegel.

[5] Andy Cush of Pitchfork gave the album a 9.1/10 review, calling it "an essential trove of music" where "each song is like a foggy transmission from a rock 'n' roll netherworld with its own ghostly canon of beloved hits".

[13] Concluding the review for AllMusic, Marcy Donelson called the album, "a sprawling epic whose uncanny, time-worn textures sound less like a vinyl alley-find and more like a cassette discovered in the cabin of a great-uncle's shipwrecked houseboat.

gave the album a Staff Pick, with reviewer Kaelen Bell writing, "Built on strains of '50s girl group pop, lush '60s psychedelia, itchy '70s radio rock, lo-fi '90s clutter and sparkling production choices grafted on from some alternate universe, Diamond Jubilee feels like the defining portrait of Cindy Lee as both artist and vessel.

[15] In year-end lists, music review publications Pitchfork, Exclaim!, and Gorilla vs. Bear named Diamond Jubilee the best album of 2024.
