Frýdlantská rozhledna, Observation tower in Frydlant, Czech Republic.

Frýdlantská rozhledna is a brick observation tower on Frýdlantská výšina (399 m) north of Frýdlant. Built in 1906–1907 to Rudolf Hampel's design on granite foundations from red, twice-fired bricks, it stands 20.8 m tall, with a viewing gallery at 18.6 m reached by an internal staircase.

A wooden lookout opened on the summit on 6 July 1890, built by the Frýdlant beautification society and named Dresslerova výšina after donor Anton Dressler. After it decayed it was replaced by the present tower, whose foundation stone was laid on 17 May 1906; built of red twice-fired brick on granite foundations to Rudolf Hampel's design, it opened on 30 April 1907.

The hill was long called Dresslerova výšina after Anton Dressler, a sponsor of the 1906–1907 brick tower, and the name stayed in use until the Second World War. In the 1950s the slopes hosted May celebrations with an open-air theatre, a concrete dance floor and stalls.

Access to the platform is via internal stairs, making the climb safe and sheltered from weather. The entrance is at ground level with straightforward access for most visitors.

The tower's brick section once housed a D-VOR radio beacon with the identification code "OKX", guiding aircraft toward Warsaw, Stockholm and Moscow. The navigation equipment moved in 1979 to a new metal tower nearby, and the beacon itself was relocated to a mast near Dětřichov.
