Lahser High School

Lahser High School was a high school in Bloomfield Township, Oakland County, Michigan, near Bloomfield Hills and in Greater Detroit. It was a part of Bloomfield Hills Schools. The school was opened in 1967. At the time it had 200 students, and enrollment later reached almost 900 students. In 2010, the decision was made to merge the school with sister school Andover High School, on Andover's grounds. In 2020, it was decided that the Lahser campus would become the site of Bloomfield Hills Middle School North following a successful bond proposal. The football program had five consecutive playoff-eligible seasons, 2002–2006, in both class 3 and class 2 MHSAA competition.

Lahser won several MHSAA state championships including: men's soccer (1999), men's/women's tennis (men's, 2002), women's lacrosse, and women's golf.

Lahser competed within the Oakland Activities Association Blue Division for football. Most of Lahser's students came from Bloomfield Hills and Bloomfield Township. Lahser's crosstown rival was Andover High School, which is the current site of the merged Bloomfield Hills High School
