Plugs are a popular type of hard-bodied fishing lure. They are widely known by a number of other names depending on the country and region. Such names include crankbait, wobbler, minnow, shallow-diver and deep-diver. The term minnow is usually used for long, slender, lures that imitate baitfish, while the term plug is usually used for shorter, deeper-bodied lures which imitate deeper-bodied fish, frogs and other prey. Shallow-diver and deep-diver refer to the diving capabilities of the lure, which depends on the size and angle of the lip, and lure buoyancy.

A plug in sanitation is an object that is used to close a drainage outlet firmly.

The insertion of a plug into a drainage outlet allows the container to be filled with water or other fluids. In contrast to screw on caps, plugs are pushed into the hole and are not put over the hole.

Plugs are most commonly encountered in the bathroom or kitchen, for use in bathtubs, wash basins or sinks.

Plug was a British comics magazine that ran for 75 issues from 24 September 1977 until 24 February 1979, when it merged with The Beezer. It was edited by Ian Gray.

A spin-off from The Bash Street Kids comic strip in The Beano, the comic was based on the character Plug who was a distinctively ugly member of the Bash Street Kids. His dog (Pug) from Pup Parade, and a new character called Chunkee the Monkey (Plug's pet monkey) accompanied him. Vic Neill mainly drew the title character's strip. The comic also had its own fan club, the Plug Sports and Social Club. The comic was inspired in part by Mad Magazine.

The Plug comic was never a big hit, possibly because, at 9 pence, it was too expensive compared to other D.C. Thomson comics at the time, which were priced at around 5 pence. According to the 2008 book The History of the Beano, for a while there were rumours of a "curse of Plug", fuelled by the fact that a number of celebrities featured in Mad magazine-style caricatures on the comic's cover died soon after, most notably John Wayne. However, the strip's use of gravure painting is still used in comics today.

Plugs in horticulture are small-sized seedlings grown in trays from expanded polystyrene or polythene filled usually with a peat or compost substrate. This type of plug is used for commercially raising vegetables and bedding plants. Similarly plugs may also refer to small sections of lawn grass sod. After being planted, lawn grass may somewhat spread over an adjacent area.

Plug plants are young plants raised in small, individual cells, ready to be transplanted into containers or a garden. Professionally raised vegetable/flowering plants in controlled conditions during their important formative period (the first 4–6 weeks) can help to ensure plant health and for plants to reach their maximum potential during the harvest/blooming period. Establishing a garden using plug plants is often easier than doing so starting from seed.

A plug (sometimes earplug or earspool), in the context of body modification, is a short, cylindrical piece of jewellery commonly worn in larger-gauge body piercings. Because of their size — which is often substantially thicker than a standard metal earring — plugs can be made out of almost any material. Acrylic glass, metal, wood, bone, stone, horn, glass, silicone or porcelain are all potential plug materials.

Plugs are commonly, and have historically, been worn in the ears. They can, however, be inserted into any piercing.

In order for a plug to stay put within a piercing, the ends of its cylindrical shape are often "flared out," or the plug is fastened in place by o-rings. Combinations of these two methods may also be used.

• A double-flared (or saddle) plug, flares outward at both ends, and is thinner towards the middle. No o-rings are needed to keep the plug in the piercing, but the fistula needs to be wide enough to accommodate the flare when the plug is initially put in.
• A single flared plug has one flared end, usually worn on the front of the piercing, and one end with no flare. The no flare end is held in place by an o-ring and may or may not be grooved. These plugs give the aesthetic of double-flared plugs without requiring that the wearer's fistulas be large enough to accommodate flares.
• A straight plug (or no-flare plug) is a typical-looking cylinder, without flares, and is kept in place by sliding o-rings against both ends of the plug. A grooved plug is a variation on the straight plug, with grooves carved in the material to hold the o-rings snug.

A plug, also known as reconciling amount, is an unsupported adjustment to an accounting record or general ledger. Ideally, bookkeeping should account for all numbers during reconciliation, i.e. when comparing two sets of accounting records to make sure they are in agreement. However, discrepancies, i.e. unintentional accounting errors can occur, for example due to data entry, or an adding or a rounding error. An organization may use a plug for an immaterial amount, because it may not be cost effective to search through numerous pages of transactions to find the error. The acceptability of a plug depends upon the amount: a plug must be immaterial in order to be justified.
