Fearless is the second studio album by American singer-songwriter Taylor Swift. The album was released on November 11, 2008, by Big Machine Records. As with her debut, Swift wrote or co-wrote all thirteen tracks on Fearless. Most of the songs were written as the singer promoted her debut album as opening act for numerous country artists. Due to the unavailability of collaborators on the road, eight songs were self-penned by Swift. Other songs were co-written with Liz Rose, Hillary Lindsey, Colbie Caillat, and John Rich. Swift also made her debut as a record producer, co-producing all songs on the album with Nathan Chapman.

Five singles spawned from Fearless. The lead single, "Love Story", is known as Swift's signature song and is her best-selling song to date, selling more than 8 million copies worldwide (according to the IFPI). It was a phenomenal crossover hit that became one of the best-selling singles of all time internationally and was once the best-selling country song of all time. The succeeding single, "White Horse", also performed well in the US. "You Belong with Me" was an international success, becoming Swift's second best-selling single and her highest position on the US Billboard Hot 100 at the time. "Fifteen" and "Fearless" followed with both achieving a platinum certification from the Recording Industry Association of America (RIAA).

Fearless was an international breakthrough and huge commercial success for Swift. It debuted at No.1 in the United States and later, became the best-selling album of 2009, selling over 5.2 million copies. It gave Swift, 20 at the time, the distinction of being the youngest artist in history to have the year's best-selling album. It went on to sell 6.95 million copies in the United States, becoming the second biggest-selling album in the last six years. Internationally, Fearless topped charts in Canada and New Zealand and achieved multi-platinum status in six countries. In all, Fearless has sold more than 8.6 million copies worldwide.
