### Abstract

We provide the classification of real forms of complex D=4 Euclidean algebra $$\mathcal{\epsilon}(4; \mathbb{C}) = \mathfrak{o}(4;\mathbb{C})) \ltimes \mathbf{T}_{\mathbb{C}}^4$$ as well as (pseudo)real forms of complex D=4 Euclidean superalgebras $$\mathcal{\epsilon}(4|N; \mathbb{C})$$ for N=1,2. Further we present our results: N=1 and N=2 supersymmetric D=4 Poincare and Euclidean r-matrices obtained by using D= 4 Poincare r-matrices provided by Zakrzewski [1]. For N=2 we shall consider the general superalgebras with two central charges.
