**Poincare-invariant deformed algebra with minimal length
**

**Abstract:**

Deformed *X,P* commutation relations invariant under symmetries of
n-dimensional Euclidean space [1] are generalized to Poincare-invariant
algebra of *(n+1)*-dimensional Minkowski spacetime with minimal length.
The existence of minimal length is proved by calculation of maximally
localized fields.
