'Gorga' is a form of artistic decoration found in the culture of Batak Toba in North Sumatra, Indonesia. The 'Gorga' motif is in the shape of flourishes and undulations. The motif is either painted or carved onto wood using three colors: white, red, black; each corresponds with different realms in the Batak Toba cosmology. The 'Gorga' motif is often found in Batak Toba architecture e.g. a Batak Toba house or objects e.g. music instruments. They are meant to protect the building or object from spiritual harm e.g. warding off evil spirits sent from neighbouring villages.

In a Batak house, Gorga motifs are carved or painted on specific areas of the house. Some examples are listed here: 'Gorga simataniari' ("sun's gorga"), a Gorga-depiction of the sun, is carved on the left and right corner of a house as a symbol of life.

Gorga ulu singa ("singa's gorga") represents the spiritual being singa of Batak mythology is placed on top of the front gable of a Batak house. Gorga boraspati depicts the gecko god Boraspati ni Tano and is usually carved on the side plank of a Batak house or barn houses; 'Gorga baraspati' is usually paired with 'Gorga adop adop' ("breasts gorga"), which represents the breasts; together, these represent fertility. 'Gorga ulu paung' is carved on the top of a Batak house. The 'Gorga ulu paung' is imbued with metaphysical power and used to ward off evil spirit coming from outside the hamlet.
