The Grammy Award for Best Rock Song stands as a notable marker in the career of Hayley Nichole Williams, an American singer, songwriter, and pianist whose work spans pop rock, emo, pop-punk, power pop, and alternative rock.

Williams was born on December 27, 1988, in Meridian, Mississippi. She has worked as a singer-songwriter and composer throughout her career, producing material across a range of overlapping genres that include emo pop and alternative rock. Her songwriting and vocal work across these genres brought her to the attention of the music industry and eventually earned her recognition from some of the field's most prominent award bodies. In addition to the Grammy for Best Rock Song, she received the Alternative Press Music Award for Best Vocalist, acknowledging her standing as a vocal performer within the alternative music community.

Williams also received the MTV Europe Music Award for Best Alternative, an honor that reflects her presence within alternative rock and its adjacent genres on an international stage. All of her recorded and performed work is conducted in the English language. The Alternative Press Music Award for Best Vocalist, in particular, connects her output directly to the community of listeners and critics who have followed alternative and emo music most closely, and it remains one of the concrete distinctions attached to her name as a singer and songwriter.
