Valentin-Heider-Gymnasium, Secondary education facility in Lindau-Aeschach, Germany

The Valentin-Heider-Gymnasium is a Gymnasium in the Aeschach district of Lindau, with three branches: languages, economics and social sciences. Its building on Ludwig-Kick-Straße dates from the 1965 move, and a sports hall was added from June 2012 to June 2013, inaugurated in July 2013. The schoolyard was redesigned in 2017. In the 2025/26 school year it had 566 pupils.

The school began as a private girls' academy between 1858 and 1859 and took its current name in 1991 after Valentin Heider, a legal scholar. The institution became a state gymnasium in 1971 and began enrolling male students in 1987.

The school's name honours Valentin Heider, the Lindau councillor who in 1655 proposed caring for the neglected youth after the Thirty Years' War and thereby founded the Lindauer Kinderfest. The children's festival is still held in Lindau, and the school carries his name since 1991.

The school stands on Ludwig-Kick-Straße in the Aeschach district, west of Lindau's old town island. It is a Gymnasium, not a university: pupils enter after primary school and prepare for the Abitur. Three branches are offered — languages, economics, and social sciences — with language sequences such as English–Latin–French or English–French–Spanish.

Valentin Heider (1605–1664) was a jurist and city councillor who represented Lindau at the peace congress in Osnabrück after the Thirty Years' War and won back rights the city had lost. In 1655 he urged the city to care for the neglected young, which began the Lindauer Kinderfest. The school has carried his name since 1991.
