The Republic of Ireland international has been in fine form this season and at the centre of speculation linking him with a possible move away from the Hawthorns.
But Long, who made the £5million switch from Reading during the summer of 2011, is happy with life under head coach Steve Clarke.
"Am I committed to West Brom for next season? Yes, I'm happy here," said the striker. "I like playing for the manager here. He is very good, and I'm learning a lot every week.
"The lads are a good bunch, the family are happy up here, so I'm not looking to move on.
"I'm concentrating on this season and hopefully getting a few more goals before the summer and kicking on from there."
