Francois Gustave Theophile Seyrig (19 February 1843 to 5 July 1923) was a German engineer, best known for designing bridges.

On 6 October 1868, he founded Eiffel and Company with Gustave Eiffel. Seyrig contributed to the Eiffel and Company project to build the Maria Pia Bridge in Porto, Portugal, which was finished in 1877. Seyrig presented a paper on the bridge to the Societe des Ingenieurs Civils in 1878.

Later he worked for the Belgian firm Societe Willebroeck in Brussels, and won the competition to build the Dom Luís I Bridge (also in Porto), beating out the project proposed by Eiffel. He began construction in 1881 and the bridge was finished in 1886.
