Miami Beach Senior High School, commonly referred to as "Beach High," is a high school located at 2231 Prairie Avenue in Miami Beach, Florida.

Miami Beach High is part of the Miami-Dade County Public Schools district; its principal was Dr. Jeanne P. Friedman, who retired at the end of the 2006-2007 school year. The new principal is Dr. Rosann P. Sidener who previously was principal at Booker T. Washington High School in Miami.

Miami Beach High opened in 1924. The school moved to its current location about 10 blocks north of the famous South Beach district in 1960. Its original mascot was the Typhoons, but this mascot was changed after the 1960 move. Beach High is one of the oldest high schools in Miami-Dade County and has a rich history. The original building at 14th and Drexel is now part of the Fienberg-Fisher Elementary School compound.

For the first 20 years of the school, it was named after Carl Fisher's mother, Ida M. Fisher. Carl Fisher provided the funds for the purchase of the land and the first principal was Mr. C. C. Carson. The school hasn't had a uniform system in its history, and currently there is no uniform policy for the students. Students though are encouraged to wear something scarlet or sliver on Fridays for the sprit of the school and wear their ID's at all times.
