SMS Seydlitz was a battlecruiser of the German Kaiserliche Marine, built in Hamburg. She was ordered in 1910 and commissioned in May 1913, the fourth battlecruiser built for the High Seas Fleet. Named after Friedrich Wilhelm von Seydlitz, Seydlitz represented the culmination of the first generation of German battlecruisers, which had started with the Von der Tann in 1906 and continued with the pair of Moltke-class battlecruisers ordered in 1907 and 1908.
Seydlitz featured several incremental improvements over the preceding designs, including a redesigned propulsion system and an improved armor layout. The ship was also significantly larger than her predecessors—at 24,988 metric tons, she was approximately 3,000 metric tons heavier than the Moltke-class ships.
