Alexis Paccard (1813 – 1867) was a French architect.
Paccard entered the École nationale supérieure des Beaux-Arts in Paris in 1830 in the workshops of Louis-Hippolyte Lebas and Jean-Nicolas Huyot. He won the Second Grand Prix in 1835 for a medical school, and won the Prix de Rome in 1841 for a "Palace of an ambassador in a foreign country."
On his return he became official inspector and architect of public buildings. He worked at the Louvre and the Tuileries under the direction of Louis Visconti. In 1854, he was an architect of the Château de Rambouillet, then Palace of Fontainebleau. In December 1863 he became professor of architecture at the Ecole, and among his students was Albert-Félix-Théophile Thomas.
