Covens and Mortier (1721 - c. 1862) was an Amsterdam publishing firm, the successor to the extensive publishing empire built by Pierre Mortier (1661 - 1711).

Covens and Mortier map are often criticized as derivative - but this is not fully the case. Pierre Mortier lived in Paris from 1681 to 1685. There he established close relationships the the greatest French cartographers of the era, including De L'Isle and D'Anville.

His business model was based upon leveraging Dutch printing technology and sophistication to co-publish state of the art French cartography. Upon Mortier's death in 1711 his firm was taken over by his son, Cornelius Mortier (1699 - 1783). Cornelius married the sister of Johannes Covens (1697 - 1774) in 1721 and, partnering with his brother in law, established the Covens and Mortier firm.

Under the Covens and Mortier imprint, Cornelius and Johannes continued in Pierre's model of publishing the most up-to-date French works with permission. They quickly became one of the largest and most prolific Dutch publishing concerns of the 18th century.

The firm and its successors published thousands of maps over a 120 year period from 1721 to the mid-1800s. During their long lifespan the Covens and Mortier firm published as Covens and Mortier (1721 - 1778), J. Covens and Son (1778 - 94) and Mortier, Covens and Son (1794 - c. 1862).
