Kristen Parker Lovell (born c. 1980) is an American trans rights activist, filmmaker, and former sex worker. After experiencing homelessness as a teenager in New York City during the late 1990s and early 2000s, Lovell went on to work for various organisations advocating for the rights of trans people and sex workers. After studying filmmaking at Lincoln Center, she went on to co-direct the documentary film The Stroll (2023), based in part on her experiences as a sex worker.

In 2007, Lovell was featured in the documentary film Queer Street, where she was interviewed about her experiences as a queer homeless youth. Lovell subsequently stated that her discomfort at the film being made by non-queer filmmakers inspired her to tell trans stories from her own trans perspective.

Lovell first purchased a camera while doing sex work in the Meatpacking District, and used it to document her experiences, as well as those of other sex workers working on the Stroll. Lovell stated that she tried to capture the "essence" of her experience, including doing sex work, experiencing discrimination as both a sex worker and a black trans woman, and also sharing camaraderie with other sex workers.

Lovell went on to study at the Artists Academy at Lincoln Center, where she had a small role in the drama film The Garden Left Behind (2019). Lovell also produced the film, and its director, Flavio Alves, stated that Lovell's experiences of living life as a trans woman led to him changing his script to better represent the experiences of trans people. Lovell also had a guest role in the sketch comedy series Random Acts of Flyness (2018).
