It is a fifth Paralympic gold medal for Smyth and Ireland's first medal of the Games.
"This is my third consecutive Games and winning my 5th Paralympic medal is incredible," said Smyth.
"It is a bit like a fairytale really, I keep coming to these major championships and winning gold and I just don’t want it to end.”
Being aware of the short time between the heats and finals, Smyth’s preparation for the final was good, he said.
"The turnaround between heats and the final wasn’t ideal," he said.
"I felt I was able to get through the heats well, doing enough without killing myself. I was ready to go and today, I know I had to step it up another notch. I was able to do that."
Earlier today in the pool, Nicole Turner qualified for the S6 50 metres butterfly final after swimming her heat this afternoon in a time of 38.44s.

Taoiseach Enda Kenny later paid tribute to the sprinter.
The Taoiseach said: "I would like to congratulate Jason on his historic sprint triumph in Rio.
"To retain the T13 100m sprint title for the third Olympics in a row is a magnificent achievement and is testament to his talent, dedication and sheer hard work.
"It is a great honour that the fastest Paralympian on the planet is an Irishman and his haul of five Olympic medals ensures his place in the pantheon of Irish sporting greats."
