Johannes Sjöstrand (1947) é um matemático sueco, especialista em equações diferenciais parciais e análise funcional.
Sjöstrand obteve um doutorado em 1972 na Universidade de Lund, orientado por Lars Hörmander. Sjöstrand lecionou na Universidade Paris-Sul sendo atualmente professor da Université de Bourgogne em Dijon.
É membro da Academia Real das Ciências da Suécia e, desde 2017, membro da Academia de Artes e Ciências dos Estados Unidos.
Foi palestrante convidado do Congresso Internacional de Matemáticos em Helsinque (1978).
