Federico Maria Molin (1753–1819) was a Catholic prelate who served as Bishop of Adria (1807–1819).
Federico Maria Molin was born in Venice on 17 November 1753. He was not a patrician because only his father, Vettor Benedetto Secondo, was patrician while his mother was not. Federico Maria became a cleric in 1763, and on 20 December 1777 he was ordained priest by Patriarch Federico Maria Giovanelli. He served as priest in the Venetian churches of San Simeone Profeta and of San Pantalon.
On 30 July 1785 he was elected in Venice with 169 votes as Abbot nullius of Asola. Pope Pius VI confirmed his election appointing him titular bishop of Apollonia on 26 September 1785. He was consecrated bishop on 9 October 1785 in the patriarchal church of San Pietro di Castello in Venice by Patriarch Federico Maria Giovanelli.
Due to the disruptions of the Napoleonic Wars, the diocese of Adria remained without bishop since 1800. With the agreement of Napoleon, Federico Maria Molin was appointed bishop of that diocese on 24 August 1807 and entered in Adria on 8 January 1808. He participated, with other Italian bishops, to the summoned by Napoleon.
Under his episcopate, in 1819, was agreed an exchange of parishes among the dioceses of Adria, Ferrara and Padova, in order to follow the natural borders marked by the rivers. He died in Adria on 16 April 1819 and he was buried in the cathedral of that town. His younger brother, Giulio (1768–1841), was also an Abbot.
