No, at least not in the games. In the cartoon Sonic Underground (which is not canon), he had a brother, Manic the Hedgehog, and a sister, Sonia the Hedgehog.

From Sonic Underground, his brother and sister are Manic and Sonia. -CNCOMICS His brother, Manic the Hedgehog, likes to steal things and although he and Sonic look alike, his hair is more wild and his fur is green. His sister, Sonia the hedgehog, is the most responsible among the three siblings. Her fur has a reddish shade and her hair has a purplish-pink color. She appears to be crushing on Knuckles the Echidna.
