This year's focus is on suicide prevention.
Today is the 10th World Mental Health Day and it's aiming to focus on suicide prevention.
Transformative Recovery College will hold an event in Mullingar where there will be information on services, song and music.
At 6 o'clock this evening, people are invited to place a message on the Reflective Tree to mark the day.
Co-Ordinator Alice McDonagh believes these events can reduce the stigma around mental health:
