Tool Time was the fictitious handyman show-within-a-show in the television sitcom, Home Improvement. It was hosted by Tim Taylor (played by Tim Allen) and Al Borland (played by Richard Karn).

Part of the show's attraction was its token "Tool Time girl", whose primary roles were to look good, be curvaceous, roll out various props and help introduce the two hosts. In the first few seasons, Pamela Anderson played Tool Time girl Lisa. When Pamela left the show, Debbe Dunning stepped in as her replacement, Heidi, who stayed until the show's cancellation.

The audience for Tool Time was the actual live studio audience for Home Improvement.
