The 1925 German presidential election was held on 29 March 1925, with a runoff on 26 April. They were the first direct elections to the office of President of the Reich (Reichsprsident), Germany's head of state during the 191933 Weimar Republic. The first President, Friedrich Ebert, who had died on 28 February 1925, had been elected indirectly, by the National Assembly, but the Weimar Constitution required that his successor be elected by the "whole German people". Paul von Hindenburg was elected as the second president of Germany in the second round of voting.

Hindenburg was the candidate of a broad coalition of the political right. Many on the right hoped that once in power he would destroy Weimar democracy from the inside and restore the pre-Weimar status quo. The two other candidates who were believed to have a chance of winning were Otto Braun of the Social Democratic Party (SPD) and Wilhelm Marx of the Centre Party. Both the SPD and Centre were members of the Weimar Coalition, the group of parties regarded as most committed to the Weimar system. Only Marx proceeded to the second round of the election.

The election was important because of the turbulent times in which it occurred and because, under the Weimar Constitution, the head of state wielded considerable power. Hindenburg would be again returned in the 1932 election and would play an important role during the rise to power of the Nazi Party. However, many of Hindenburg's 1925 backers were subsequently disappointed. Although in the years that followed his election many questioned the constitutionality of certain of his actions, Hindenburg never attempted to overthrow the Weimar constitution outright.

Paul Ludwig Hans Anton von Beneckendorff und von Hindenburg (pronounced [ˈpaʊl ˈluːtvɪç hans ˈantoːn fɔn ˈbɛnəkŋ̍dɔʁf ʔʊnt fɔn ˈhɪndn̩bʊʁk] (listen); abbreviated pronounced [ˈpaʊl fɔn ˈhɪndn̩bʊʁk] (listen); 2 October 1847 – 2 August 1934) was a German general and statesman who led the Imperial German Army during World War I and later became President of Germany from 1925 until his death in 1934. During his presidency, he played a key role in the Nazi seizure of power in January 1933 when, under pressure from advisers, he appointed Adolf Hitler as Chancellor of Germany.

Paul von Hindenburg was born on 2 October 1847 to a family of minor Prussian nobility in Posen. Upon completing his education as a cadet, he enlisted in the Third Regiment of Foot Guards as a second lieutenant. He then saw combat during the Austro-Prussian and Franco-Prussian wars. In 1873, he was admitted to the prestigious Kriegsakademie in Berlin where he studied for three years before being appointed to the Army's General Staff Corps. Later in 1885, he was promoted to the rank of major and became a member of the Great General Staff. Following a five-year teaching stint at the Kriegsakademie, Hindenburg steadily rose through the army's ranks to become a lieutenant-general by 1900. Around the time of his promotion to General of the Infantry in 1905, Count Alfred von Schlieffen recommended that he succeed him as Chief of the Great General Staff but the post ultimately went to Helmuth von Moltke in January 1906. In 1911, Hindenburg announced his retirement from the military.

Following World War I's outbreak in July 1914, he was recalled to military service and quickly achieved fame on the Eastern Front as the victor of Tannenberg. Subsequently, he oversaw a crushing series of victories against the Russians that made him a national hero and the center of a massive personality cult. By 1916, Hindenburg's popularity had risen to the point that he replaced General Erich von Falkenhayn as Chief of the Great General Staff. Thereafter, he and his deputy, General Erich Ludendorff, exploited Emperor Wilhelm II's broad delegation of power to the German Army to establish a de facto military dictatorship that dominated national policy for the rest of the war. Under their leadership, Germany secured Russia's defeat in the east and achieved advances on the Western Front deeper than any seen since the conflict's outbreak. However, by the end of 1918, all improvements in Germany's fortunes were reversed after the German Army was decisively defeated in the Second Battle of the Marne and the Allies' Hundred Days Offensive. Upon his country's capitulation to the Allies in the November 1918 armistice, Hindenburg stepped down as Germany's commander-in-chief before retiring once again from military service in 1919.

In 1925, Hindenburg returned to public life to become the second elected president of the German Weimar Republic. While he was personally opposed to Adolf Hitler and his Nazi Party, he nonetheless played a major role in the political instability that resulted in their rise to power. Upon twice dissolving the Reichstag in 1932, Hindenburg ultimately agreed to appoint Hitler as Chancellor of Germany in January 1933 when the Nazis won a plurality in the November elections. In response to the Reichstag Fire allegedly committed by Marinus van der Lubbe, he approved the Reichstag Fire Decree in February 1933 which suspended various civil liberties. Later in March, he signed the Enabling Act of 1933 which gave the Nazi regime emergency powers. After Hindenburg died the following year, Hitler combined the presidency with his office as chancellor before proceeding to declare himself Führer und Reichskanzler des deutschen Volkes (i.e. "Leader and Reich Chancellor of the German People") and transformed Germany into a totalitarian state.
