Marjory Stoneman Douglas High School (MSDH) is a four-year, comprehensive, U.S. public high school located in Parkland, Florida, in the Miami metropolitan area. It is a part of the Broward County Public School district, and it is the only public high school in Parkland, serving almost all of the limits of that city as well as a section of Coral Springs.^[4][5][6] The school is named after the writer Marjory Stoneman Douglas.

In 2018, the school became the scene of a deadly mass shooting carried out by a 19-year-old former student.

Marjory Stoneman Douglas High School was named after the Everglades environmentalist Marjory Stoneman Douglas. The school opened in 1990, the year of her centennial^[7] with students in grades 9 through 11, most of whom transferred from nearby schools Coral Springs High School and J. P. Taravella High School. The first senior class graduated in 1992.

On February 14, 2018, the school gained national attention when a shooting occurred at the campus, leaving 17 dead and 17 more wounded. The alleged gunman, who was a former student at the school, was apprehended hours later.^[8][9] Authorities have charged the gunman with first-degree murder in response to the shooting, and legal proceedings were ongoing as of January 2019.^[10][11]

Students from Stoneman Douglas were instrumental in changing Florida law, on March 4, 2018, to raise the legal rifle-owner age from 18 to 21, with a three-day wait,^[12] after they had helped to organize nationwide student protests, following the shooting.^[13][12][14]

In 2019, Sarah Lerner, an English and Journalism teacher at the high school during the shooting, edited and publish a book called "Parkland Speaks". This book has poems, pictures, stories and much more created by the survivors of shooting. The Publisher, Random House Children's Books, donates to Shine MSD, INC., which is an organization that the students of MSD put together to help the families of the victims.

The MSD athletics department operates programs in football, volleyball, lacrosse, softball, tennis, track, water polo, basketball, cheerleading, soccer, wrestling, swimming, cross country, and golf.^[15]

The cheerleading squad at Marjory Stoneman Douglas High School received international attention in 2012 when Coach Melissa Prochilo, who had come to MSD from Coral Glades High School,^[16] was fired in response to complaints from parents. Parents complained about being charged thousands of dollars for their children to participate in the program, and alleged that the coach mishandled the team's finances and encouraged bullying, one saying "(Coach Prochilo) herself bullied some of the girls."^[17][18]

Newsweek magazine's 2009 national ranking of high schools rated Douglas as No. 208 in the U.S., and No. 38 in Florida, which was the highest ranking of any school in Broward County.^[19]

Marjory Stoneman Douglas High School had a Florida Comprehensive Assessment Test (FCAT) school grade of "A" for the 2011–2012 academic school year.^[20]
