Phaedra is the fifth studio album by German electronic music group Tangerine Dream. It was recorded during November 1973 at The Manor in Shipton-on-Cherwell, England and released on 20 February 1974 through Virgin Records. This is the first Tangerine Dream album to feature their now classic sequencer-driven sound, which is considered to have greatly influenced the Berlin School genre.

The album marked the beginning of the group's international success and was their first album released on the Virgin label. It achieved six-figure sales in the UK, reaching number 15 in the UK Albums Chart in a 15-week run, with virtually no airplay, only by strong word of mouth. It also earned the group a gold disc in seven countries, though in their native Germany it sold barely 6,000 units. The album title refers to Phaedra of Greek mythology.
