Abstract: An action for four-dimensional extended string Newton-Cartan gravity can be obtained as a nonrelativistic limit of the Einstein-Hilbert action in General Relativity augmented with a term that contains an auxiliary two-form and one-form gauge field that both have zero flux on-shell. The construction of four-dimensional extended string Newton-Cartan gravity which is based on a central extension of string Newton-Cartan algebra will be discussed.
