A Steiner point (named after Jakob Steiner) may refer to:

• Steiner point (computational geometry), a point added in solving a geometric optimization problem to make its solution better
• Steiner point (triangle), a certain point on the circumcircle of a given triangle
• One of 20 points associated with a given set of six points on a conic; see Pascal's theorem § Hexagrammum Mysticum

  • The median of three vertices in a median graph, the solution to the Steiner tree problem for those three vertices
  • The Fermat point of a triangle, the solution to the Steiner tree problem for the three vertices of the triangle
