"I Think We're Alone Now" is a song written and composed by Ritchie Cordell that was the title selection for a highly successful album released by the American recording artists Tommy James and the Shondells. "I Think We're Alone Now" was a 1967 US hit for James and the Shondells, reaching number 4 on the Billboard Hot 100 chart. The song has since been covered several times by other artists. The late 1987 recording by Tiffany reached number 1 on the charts of various countries including the US, UK, Canada, and New Zealand. One month earlier, another Tommy James song had also hit number 1—Billy Idol's version of "Mony, Mony". Other cover versions have also charted, including those by The Rubinoos (number 45 US, 1977) and Girls Aloud (number 4 UK, 2006).

"I Think We're Alone Now" was a 1967 hit song for Tommy James and the Shondells, as noted above, reaching number 4 on the Billboard Hot 100 chart during a 17-week stay. The recording was produced by Ritchie Cordell and Bo Gentry. Cordell wrote or co-wrote many songs for James, including the follow-up single "Mirage" and its B-side "Run, Run, Baby, Run", and 1968's "Mony Mony". Rock critic Lester Bangs called the single "the bubblegum apotheosis".

Like many early Tommy James and the Shondells releases, only band members Tommy James and Eddie Gray were featured on the record. (The rest of the band provided background vocals.) Studio musicians were used as the rest of the rhythm section to back up the Shondells. These musicians include Artie Butler playing Ondioline electric keyboard, Al Gorgoni on guitar, Joe Macho on bass, Paul Griffin on piano, and Bobby Gregg on drums.
