Paul Friedrich Theodor Eugen, Reichsfreiherr von Maucler (30 May 1783 – 28 January 1859) was a Württemberg politician and bibliophile.

In 1809, as General State Commissioner for the Kingdom of Württemberg, he took over the territory around Mergentheim, which had previously belonged to the Teutonic Order.

While carrying out this mission, he fell into the hands of rebellious peasants, but was eventually released from captivity unharmed.

[3] In 1815, Maucler was a member of the Estates meetings convened by King Frederick I, where he acted in 1817 as a representative of those entitled to vote.

In 1848, the conservative politician, who was particularly concerned with the organization of the national territory, which had grown considerably after secularisation, retired.
