"Amanda" is a power ballad by American rock band Boston written by Tom Scholz. The song was released as the first single from the band's third album, Third Stage, in 1986, six years after it was recorded.

Third Stage is the third studio album by the American rock band Boston, released on September 26, 1986, on MCA Records. It was recorded at Boston co-founder Tom Scholz's Hideaway Studio over a long, strained, six-year period "between floods and power failures". Scholz and vocalist Brad Delp were the only original members. The lyrics invoke themes of aging and working through stages in life. The first track and lead single, "Amanda", became a number one hit and one of the group's best known songs. The album itself was eventually certified 4× platinum by the RIAA.
