Tirsa With is a 19 year old queer black activist and poet.

She is the founding chair of the political youth organisation RADICAAL, which aims to provide youth with a platform to strive for radical equality. RADICAAL is the youth branch of the political party formerly known as Artikel 1, of which Tirsa is a board member as their youth representative. She also studies sociology and culture at Amsterdam University College.

Tirsa loosely identifies as Surinamese, Dutch, woman, genderqueer, queer and black feminist. She started writing as an act of self care, which results in poetry that is personal, melancholic and socially critical.
