Necessary and suffcient conditions for global Gevrey hypoellipticity are proposed. / Neste trabalho estudamos a Hipoeliticidade Global Gevrey em R² para uma classe de operadores diferenciais parciais lineares de 1ª ordem, com coeficientes em Cw2χ (R)Condições necessárias e suficientes para a Hipoeliticidade Global Gevrey são propostas.
