Christine Frances Quinlan (born May 7, 1986) is an American singer-songwriter, guitarist and visual artist best known for fronting Philadelphia indie rock band Hop Along.

Quinlan was raised in northern New Jersey and Quakertown, Pennsylvania, and was an active reader in their youth. Quinlan was encouraged by their mother to create art, and was later encouraged to pursue art as a career by their high school art teacher.

Their parents, whom they have described as "big music fans", introduced them to artists such as Bob Dylan, Cat Stevens, and The Kinks at an early age. They initially attempted to learn to play the electric guitar at age 13, but became frustrated and gave up. However, after their brother Andrew introduced them to musicians such as Ani DiFranco, Fiona Apple, and Lauryn Hill, they revisited the instrument and were more successful. They began songwriting and working on musical projects with their brother. They worked as a house painter during this time.

Quinlan began playing shows in Philadelphia through connections made on Myspace and in the punk rock and hardcore punk scenes. Quinlan was then discovered by Mattie Canino of RVIVR and Latterman, who further supported them early in their career. In the mid-2000s, Quinlan began a solo acoustic project in college at Maryland Institute College of Art. During this time, they released their debut EP, Songs of the Sea.

Quinlan recorded their first solo album, Freshman Year, under the name Hop Along, Queen Ansleis, in 2005, between their freshman and sophomore years of college. They distributed the album on burned CDs. After graduation, their other brother, Mark, joined them on drums as they developed the project, which was renamed Hop Along. Hop Along's debut album Get Disowned was released in 2012 to critical acclaim. Hop Along's 2015 studio album Painted Shut was also praised by critics for its "immediacy and emotional depth", led by Quinlan's voice. Quinlan lived in Philadelphia in the mid-2010s, where they wrote the lyrics to the band's fourth album, Bark Your Head Off, Dog.

Quinlan's debut solo album, Likewise was released on January 31, 2020 through Saddle Creek Records. Hop Along guitarist Joe Reinhart appears on the album performing guitar and bass. Quinlan created the album's cover art, as they have done for every prior album released under Hop Along.

Quinlan was scheduled to perform at SXSW in 2020, but this appearance was cancelled due to COVID-19 restrictions.

Quinlan recorded the song "Another Season", which plays through the end credits of the 2024 psychological horror drama film I Saw the TV Glow.
