Marten van Valckenborch or Marten van Valckenborch the Elder, was a Flemish Renaissance painter, mainly known for his landscapes and city scapes. He also made allegorical paintings and some portraits. After commencing his career in the Spanish Netherlands, he later migrated to Frankfurt in Germany where he and other members of his extended family of artists played an important role in local artistic developments.

Marten van Valckenborch was born in Leuven in what would become one of the most prominent Flemish families of artists. Spanning three generations, 14 artists are recorded in the family of whom his younger brother Lucas the Elder and his own sons, Frederik van Valckenborch and Gillis van Valckenborch, were the most important personalities.

Marten joined the Guild of St Luke in Mechelen on 13 August 1559. On 3 December 1563 Gysbrecht Jaspers was recorded as his pupil. The early biographer Karel van Mander reported that Marten van Valckenborch learned to paint landscapes in Mechelen, which was known at the time as a center for oil and water-colours and especially landscape painting. In 1564 Marten moved to Antwerp, where his brother Geraard van Valckenborch trained with him until 1568.

At the start of the iconoclastic fury of the Beeldenstorm in 1566 he left town with his brother Lucas. The brothers made a trip from Liège to Aachen along the Meuse (river), painting river valley views. In 1566 the artist was in Aachen, where he was joined in 1570 by his brother Lucas. In Aachen, the two brothers were also joined for two years by Hans Vredeman de Vries, friend and fellow artist. Hendrik van Steenwijk the Elder also resided in Aachen where he married Marten van Valckenborch's daughter. Marten became a citizen of Aachen in 1573.

Marten was recorded back in Antwerp in the years 1575-1576 and was referred to as an ouderman (elder) in the Antwerp Guild of St Luke in 1584. He left the Spanish Netherlands after the Fall of Antwerp in 1585.

He was registered in Frankfurt from 1586 onwards. On 7 July 1586 Marten became a citizen of Frankfurt, together with his son-in-law Hendrik van Steenwijk the elder. At the beginning of 1593 his brother Lucas joined Marten in Frankfurt after a residence in Austria.

Marten and his brother operated in Frankfurt a large workshop, which his sons Gillis and Frederik joined. Marten died in 1612 in Frankfurt.
