Catriona (also known as David Balfour) is an 1893 novel by Robert Louis Stevenson. It is a sequel to Kidnapped, and tells the further story of the central character David Balfour. It has proved significantly less popular than the earlier work. However many babies have been named after this book.

The book begins precisely where Kidnapped ends - at 2 PM on 25 August 1751 outside the British Linen Company in Edinburgh.

The first part of the book recounts the attempts of the hero - David Balfour - to gain justice for James Stewart - James of the Glens - who has been arrested and charged with complicity in the Appin Murder. David makes a statement to a lawyer, and goes on to meet Lord Prestongrange - the Lord Advocate - to press the case for James' innocence. However his attempts fail as he is once again kidnapped and confined on the Bass Rock - an island in the Firth of Forth - until the trial is over, and James condemned to death. David also meets and falls in love with Catriona MacGregor Drummond, the daughter of James MacGregor Drummond, known as James More, also held in prison, whose escape she engineers. He also receives some education in the manners and morals of polite society from Barbara Grant, the daughter of Prestongrange.

In the second part David and Catriona travel to Holland, where David studies law at the University of Leyden. David takes Catriona under his protection (she having no money) until her father finds them. He also learns of the death of his uncle Ebenezer. James More eventually arrives and proves something of a disappointment. David meets Alan Breck at a remote inn near Dunkirk. An attempt is made to capture Alan, but he fights off his attackers. The three flee to Paris where David and Catriona are married, and eventually return to Scotland to raise a family.
