The 59-year-old artist, who communicates with limited verbal expression, was awarded the £25,000 prize for her installation "Hanging Sculpture 1-10" and her contribution to the exhibition "Conversations."
Disability charity Sense praised Kalu's victory as "long overdue" and "richly deserved," highlighting its importance in showcasing the capabilities of disabled artists.
Kalu's artistic facilitator, Charlotte Hollinshead, spoke about the ongoing struggle against discrimination faced by differently-abled artists, stating that Kalu's win helps to dismantle such prejudice.
The award ceremony was held in Bradford, this year’s UK City of Culture, where an exhibition featuring works by all four Turner Prize finalists is open until 22 February.
