San Marco Evangelista in Agro Laurentino is a Catholic church in Rome, Italy on the Piazza Giuliani e Dalmati in the Giuliano-Dalmata quarter.

The dedication to Saint Mark alludes to the presence in the area of Istrian and Dalmatian refugees (who fled the Julian March after the Second World War), as does the Lion of St. Mark above the portico.

It was erected between 1970 and 1972 to plans of Ennio Canino and Cardinal Vicar Angelo Dell'Acqua consecrated it on 29 May 1972.

In the crypt is a series of mosaics depicting the patron saints of the native nations of the Giuliano-Dalmati, i. e., northeastern Adriatic, refugees.

Since 1973 it has been the seat of the titulus of "San Marco in Agro Laurentino".
