It took until the 86th minute for Vasco to open the scoring through midfielder Douglas before Fabiano put the result beyond doubt in stoppage time on Sunday, reports Xinhua news agency.
Botafogo were forced to play the final half hour with 10 men after full-back Marcelo was shown a second yellow card for a rash challenge on Guilherme Costa.
His teammate Bruno Silva was also shown a red card after the final whistle for dissent towards referee Bruno Araujo.
The result made Vasco the most successful team in the history of the Rio Cup, surpassing Flamengo's tally of nine titles.
