Maria Gyllenstierna af Lundholm (born in 1716, died in 1783) was a Swedish baroness and a patron of arts.

[3] Maria Gyllenstierna af Lundholm donated an altarpiece to the St. Peter's Church in Siuntio, depicting Christ in Gethsemane.

This new altarpiece features gilded frames with the coats of arms of the Reuterholm and Gyllenstierna af Lundholm families at the bottom.

[4] In 1774, the cathedral chapter granted Maria Gyllenstierna af Lundholm a specific burial right.

[5] In 1815, all removable items were evacuated from the chapel to Sweden after Suitia Manor and all of Finland had become a part of the Russian Empire as the result of the Finnish War.
