2015 Hamilton Tiger-Cats season

The 2015 Hamilton Tiger-Cats season was the 58th season for the team in the Canadian Football League and their 66th overall. The Tiger-Cats finished in second place in the East Division with a 10–8 record and hosted a playoff game for the third consecutive season. The Tiger-Cats defeated the Toronto Argonauts in the East Semi-Final, but lost to the Ottawa Redblacks in the East Final, ending their quest to compete in three straight Grey Cups. This marked the first full season for the team playing at their new stadium, Tim Hortons Field. The Tiger-Cats played their first four games on the road due to stadium conflicts with the 2015 Pan Am Games. When they returned to their home field, they sold out all nine regular seasons games, which was the first time that the franchise had done that since 1973.
