"Obscene Phone Caller" is a song recorded by American singer Rockwell, released by the Motown label in 1984, as the second single from his debut studio album Somebody's Watching Me.

Rolling Stone wrote that "Obscene Phone Caller" "plays into the same paranoia as 'Somebody's Watching Me,' yet nods more to upbeat pop than Rockwell’s more sinister-sounding breakthrough hit.

The back-up harmonies are smooth, with a sophisticated lead vocal delivering the paranoid lines — timely lyrics, in the year of Big Brother, for which Rockwell has become well-known.

[9] Billboard Magazine declared that despite the fact that "Obscene Phone Caller" does not have Michael Jackson on backing vocals like "Somebody's Watching Me" did, its "mannered speech, bouncy beat and paranoid obsession" make it comparable to its predecessor.

[10] The Courier-News critic Marc Hawthorne considered the Jacksons' single "Torture", released later in 1984, to be similar to "Obscene Phone Caller".
