Competition between various types of interaction leads to complex phase diagrams, exhibiting multicritical points. Bicritical points appear due to uniaxial assymmetry, resulting e.g. from uniaxial stress. These may become tetracritical when cubic symmetry exists. Tricritical and bicritical points appear in metamagnets. Tetracritical points exist for randomly mixed ferromagnets and antiferromagnets. Competing interactions also lead to new types of critical behaviour, e.g. "dipolar", "cubic", etc. All of these may be affected by interactions with elastic degrees of freedom, random impurities, etc. Present theoretical understanding of these phenomena, based mainly on renormalization group arguments, is reviewed, and relevant experiments are mentioned.
