Susanne Ditlevsen (born 1965) is a Danish mathematician and statistician, interested in mathematical biology, perception, dynamical systems, and statistical modeling of biological systems. She is a professor in the Department of Mathematical Sciences of the University of Copenhagen, where she heads the section of statistics and probability theory.

Early life Ditlevsen was born in Denmark. She graduated from in 1983. She was an actress before she became a researcher.

In 2023, she and her brother Peter, a climate scientist, published an article predicting that the Atlantic Meridional Overturning Circulation has a chance of collapsing between 2025 and 2095 (95% confidence interval), with the statistical average of the predictions being 2057 (updated in August 2025 to between 2037 and 2109, with average of 2065). When this tipping point is reached, it will have severe consequences to the world's climate, especially of northern Europe (see Effects of AMOC slowdown).
