Mental Health Nurses Day, also known as National Mental Health Nurses Day, is observed worldwide every February 21 to recognize the vital contributions of mental health nurses and promote mental health nursing as a rewarding career. Established in the United Kingdom in 2019 by a group of mental health nurses, the day aims to celebrate the hard work of these professionals who care for patients experiencing various mental health issues, including addiction, anxiety disorders, and schizophrenia. Canada joined the celebration in 2024, marking its first federally recognized National Mental Health Nurses Day. Activities typically include events organized by mental health nurses, employers, professional organizations, and educators, with a focus on sharing experiences and encouraging new entrants into the field. Participants often use social media hashtags like #MHNursesDay and #MentalHealthNursesDay to spread the word. The day highlights the importance of understanding, empathy, and professionalism in mental health nursing.
