Fort Roupel (Greek: Οχυρό Ρούπελ) is a fortress at the north border of Central Macedonia, Greece, built-in 1914. It became part of the fortifications of the Metaxas Line in the 1930s and became famous for its defence during the German invasion of Greece in April 1941.

The Rupel fortifications are not far from the Serres-Promachonas national road, which leads to the Greek-Bulgarian border. They are just a short distance from the border in the narrow Rupel Gorge, through which the Strymon River flows. This place is strategically important for entry to Greek or Bulgarian territory and was fortified in 1914.

During World War I, on 25 May 1916, the royal Greek government of Athens permitted the surrender of the fortress to the Germans and their Bulgarian allies as a counterbalance to the Allied forces that had been established in Thessaloniki. The German-Bulgarian troops then proceeded to occupy most of eastern Macedonia without resistance. This act led to the outbreak of a revolt of Venizelist Army officers in Thessaloniki and the establishment of the Provisional Government of National Defence under Entente auspices there, opposed to the official government of Athens and King Constantine I, cementing the so-called "National Schism".

The fort also became famous during World War II, when the advance of the German armies on that front sector was halted here. On the eve of World War II, Fort Roupel was incorporated into the Metaxas Line, a new line of defence that was built to repel an invasion of Greece from Bulgaria. For three days, the fort held out against German attack and was only abandoned by its men after the surrender of the Greek army in Thessaloniki.

Today one of the fortification's galleries is open to visitors, as is a small museum and the pavilion the visitors, the observatory and the memorial of fallen soldiers.
