The Smolenskoye Cemetery (in German Smolensker Friedhof) is a Lutheran cemetery on Dekabristov Island in Saint Petersburg, Russia. It is one of the largest and oldest non-orthodox cemeteries in the city. Until the early 20th century it was one of the main burial grounds for ethnic Germans.
The Lutheran cemetery on Dekabristov Island is known to have existed in 1747. The Smolenka River divides it from the Smolensky Orthodox Cemetery on Vasilievsky Island. This cemetery contained the burials of the parishioners of the Evangelical Lutheran Church of Saint Katarina and the Catholic Church of St. Catherine, including Leonhard Euler, Xavier de Maistre, Germain Henri Hess, José de Ribas, Moritz von Jacobi, Agustín de Betancourt, Jean-François Thomas de Thomon, Ludvig Nobel, Fyodor Litke, Georg Friedrich Parrot, Karl Nesselrode, Vladimir Lamsdorf and Vasily Radlov.
