"Vasoline" is a song by American rock band Stone Temple Pilots from their second album, Purple. The song was the second single of the album, reaching number one on the Billboard Mainstream Rock Tracks chart for two weeks. The song's odd-sounding intro was created by Robert DeLeo, who ran his bass through a wah-wah pedal to get the said effect. The song's lyrics were written by vocalist Scott Weiland. "Vasoline" also appears on the greatest hits compilation album Thank You. A live version also appears on The Family Values 2001 Tour compilation.

Purple is the second studio album by the American rock band Stone Temple Pilots, released on June 7, 1994, by Atlantic Records. The album, building on the foundation laid by the band's debut album Core (1992), was a major commercial success, debuting at No. 1 on the Billboard 200 with 252,000 copies sold in its first week. It remained at the top of the chart for three weeks, eventually selling over six million copies. It spawned a number of successful singles; "Vasoline" and "Interstate Love Song" both topped the Mainstream Rock Tracks chart and reached number 2 on the Modern Rock Tracks chart, while "Big Empty" also reached the top ten on both charts. Lesser known album cuts "Pretty Penny" and "Unglued" were released as promotional radio singles.
