Mary, Queen of Peace is a Catholic church on the Sammamish Plateau started in 1987. At the time, more residents were moving to the area and the parish was made up of Catholic church members from Issaquah, Carnation and Redmond.
Mary, Queen of Peace held its first Mass in October of that year. That service was held on what is now Trinity Lutheran College. It was not until 1990 when Mary, Queen of Peace welcomed worshippers at its current location. It expanded in 2002.
One estimate placed the congregation at more than 2,100 families.
