Patrick M. Lawlor (born November 30, 1951) is a video game and pinball machine designer.
Pat Lawlor had originally been a video game designer and had entered the coin-operated game design industry in 1980, working for Dave Nutting Associates. Lawlor's pinball career began as an engineer for Williams in 1987, when he co-designed a dual-playfield machine called Banzai Run with Larry DeMar. In 1988, he was assigned his first individual design project, a machine entitled Earthshaker!, which was released in January 1989. Notably, Earthshaker! was the first pinball machine with a shaker motor.[citation needed]
