The Church of San Nicolás de Soria (Spanish: Iglesia de San Nicolás) is now only ruined remnants of a Romanesque-style, Roman Catholic, former church located in Soria, Spain.

It was declared Bien de Interés Cultural in 1962.

[citation needed] Part of the apse and some side walls remain: in 1858, the nave roof was brought down.

In 1978, during some restoration works, frescoes depicting the murder of Saint Thomas of Canterbury were discovered in one of the remaining walls of the church.
