"Iceblink Luck" is a single by Scottish band Cocteau Twins, released by 4AD Records in August 1990. It was the first single from the Heaven or Las Vegas album and the band's first single to be released in the United States. It was the band's second single to reach the Top 40 in the UK Singles Chart, peaking at No. 38. Featuring a more accessible, intelligible sound that Allmusic commented was 'almost a rave-up', the single managed to achieve airplay on the UK's national radio, and the album proved to be the band's highest charting release in the UK.
