St. Mark's Church (Danish: Sankt Markus Kirke) is a church at the end of Julius Thomsens Plads in the Frederiksberg district of Copenhagen, Denmark.

It was consecrated on 9 November 1902 at a ceremony attended by Bishop Kultus Minister J. C. Christensen.

The area was still quite undeveloped on its completion but the surrounding buildings were built from 1903 to 1904 according to a symmetrical plan by Andreas Clemmensen.

Over the main portal there is a mosaic by Oscar Willerup depicting Saint Mark the Evangelist with a quill and a winged lion, his symbol.
