A squeegee or squilgee is a tool with a flat, smooth rubber blade, used to remove or control the flow of liquid on a flat surface. It is used for cleaning and in printing.

The earliest written references to squeegees date from the mid-18th century and concern deck-cleaning tools, some with leather rather than rubber blades. The name "squeegee" may come from the word "squeege", meaning press or squeeze, which was first recorded in 1783. The closely related "squeedging" was reportedly first used in 1782, in the Covent Garden Theatre, during the performing of the comedy Which is the Man? by Hannah Cowley.

The best-known of these tools is probably the hand-held window squeegee, used to remove the cleaning fluid or water from a glass surface. A soapy solution acts as a lubricant and breaks up the dirt, then the squeegee is used to draw the now water-borne dirt off the glass leaving a clean surface. Some squeegees are backed with a sponge which can soak up soapy water from a bucket for application to a dirty window.

Squeegees were in use for cleaning windows by 1918 when an American book on navy jargon explained that a deck-cleaning tool called a squeegee was "used in civil life to clean windows". This is the earliest written reference to a window cleaning squeegee given by the Oxford English Dictionary. (For earlier uses see "floor cleaning" section below.)

With the development of the skyscraper in the 20th century, a more efficient tool for the cleaning of window exteriors was needed. Professional window washers began using the Chicago squeegee, a bulky tool with two heavy pink rubber blades. Changing the blades required the loosening of twelve separate screws. The modern single-blade window cleaning squeegee was patented by Ettore Steccone in 1936, who dubbed it the "New Deal". It was made of lightweight brass with a very flexible and sharp rubber blade. Steccone began a manufacturing process and sold the product in his garage. The Ettore Products Co. is still the leader in the squeegee market today. Squeegee kits can include a telescoping pole to extend the washer's reach.

Simple squeegees are made in various shapes for household use, including the cleaning of shower doors, bathroom tile, and garage floors.

There is a double-sided squeegee model. On one side is the classic squeegee, on the other side is a soft sponge for applying the detergent. The squeegee is usually sold with a short handle.

Companies produce squeegees for home use, as well as professional squeegees for use by cleaning companies and private glass cleaners who provide services to the public.
