The (Royal) Institute for the Blind (Danish: Blindeinstituttet) is a listed, Historicist building on Kastelsvej in the Østerbro district of Copenhagen, Denmark.

Built in two stages in 1858 and 1880 to a design by Ferdinand Meldahl, it was the first special school for blind students in Denmark and was listed in 1977.

The Institute for the Deaf had been built as an arrowhead-shaped revelin which could easily be converted into a defensive structure in the event of a hostile attack.

The three-winged complex had room for 60 students, 30 boys and 30 girls, each housed in their lateral wing.

The four-winged complex is built in red brick and has a grey tile roof.
