Johan Niclas Byström (1783-1848) was a Swedish sculptor.
Byström was born at Filipstad and went to Stockholm the age of twenty, studying there for three years under Johan Tobias Sergel.
In 1809 he gained the prize of the Royal Academy of Arts, and in the following year visited Rome.
He sent home a beautiful work, "The Reclining Bacchante", in half life size, which raised him at once to the first rank among Swedish sculptors.
On his return to Stockholm in 1816 he presented the crown prince (the later king Charles XIV) with a colossal statue of himself, and was entrusted with several important works.
