A drinking straw is a utensil that is intended to carry the contents of a beverage to one's mouth. Disposable straws are commonly made from plastics. However, environmental concerns related to plastic pollution and new regulation have led to rise in reusable and biodegradable straws. Following a rise in regulation and public concern, some companies have even voluntarily banned or reduced the number of plastic straws used. Alternative straws are often made of reusable materials like silicone or metal or alternative disposable and biodegradable materials like paper, cardboard, pasta, or bamboo.

A straw is used by placing one end in one's mouth and the other in a beverage. By employing suction, the air pressure in one's mouth drops causing atmospheric pressure to force the liquid through the straw and into the mouth. Drinking straws can be straight or have an angle-adjustable bellows segment. Straws have been used since earliest recorded history, with the first extant straws dating from the 4th century BCE. Different traditional drinks and foods use straws designed for explicit purposes, such as the "straw and sieve" bombilla used to drink the mate infusion common to South America. Since the early 20th century, mass-production of straws from plastic and other industrial products such as cellophane has increased the widespread availability of disposable straws.

Though most straws are used by able-bodied peoples, they play an important role in food and drink access for people with physical disabilities that affect their ability to swallow, hold glassware, or carry the weight of drinks or other liquids.Straws can also be an important part of both child and elderly care or in recovery from certain medical procedures such as dental work, making it safer and easier to consume liquids. However, the use of straws may not always be advisable depending on the health situation.
