Spurs started brightly and took the lead when Emmanuel Adebayor knocked in Gareth Bale's driven cross after Petr Cech appeared to miss it.
Chelsea improved though and deservedly pulled level when Daniel Sturridge turned in Ashley Cole's low cross from close range. Cole looked to have inadvertantly handled the ball during the move.
In the second hald Didier Drogba hit the post and Ramires headed wide for the Blues, while Spurs almost snatched victory when John Terry hacked Adebayor's goalbound shot clear.
The result means Spurs stay in third place in the Premier League, two points ahead of fourth-placed Chelsea, but nine points behind leaders Manchester City.
