Parallel may refer to:

In geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. By extension, a line and a plane, or two planes, in three-dimensional Euclidean space that do not share a point are said to be parallel. However, two lines in three-dimensional space which do not meet must be in a common plane to be considered parallel; otherwise they are called skew lines. Parallel planes are planes in the same three-dimensional space that never meet.

Parallel lines are the subject of Euclid's parallel postulate. Parallelism is primarily a property of affine geometries and Euclidean space is a special instance of this type of geometry. Some other spaces, such as hyperbolic space, have analogous properties that are sometimes referred to as parallelism.

is a Japanese shōnen manga by Toshihiko Kobayashi. It tells the story of two high school students, Shinnosuke Nekota and Sakura Hoshino, who are forced to live together in the same house when their parents become unofficially engaged and leave the country for their work. The manga spans four volumes, comprising a total of 19 chapters as well as a one-chapter special.

Parallel is a compilation album by the intelligent dance music artists Ken Downie, Ed Handley and Andy Turner, aka The Black Dog, which was released in 1995 on double vinyl and CD. The album compiles three EPs released on the GPR label in 1991 and 1992.

The parallel operator ∥ (pronounced "parallel") is a mathematical function which is used especially as shorthand in electrical engineering. It represents the reciprocal value of a sum of reciprocal values and is defined by:

$\begin{array}{rlcl} \|:\ & \overline{\mathbb{C}} \times \overline{\mathbb{C}} &\to& \overline{\mathbb{C}}\\ & (a,b) &\mapsto& a \| b = \frac{1}{\frac{1}{a} + \frac{1}{b}} \end{array}$

That is, it gives half of the harmonic mean of two numbers a and b.

Parallel is a video feature compiling all of R.E.M.'s Automatic for the People and Monster-era promotional videos, as well as several recorded for this release alone. It was released on video on May 30, 1995, and on DVD format on August 22, 2000, both on the Warner Brothers label.

The release, which runs at 70 minutes, features promotional videos to all of the band's singles from Automatic for the People and all but one from Monster ("Tongue" had not been released as a single until after this compilation). Also included are several avant-garde clips excerpted from 1995 tour films, ranging from ten seconds to two minutes, playing in between each song, as well as an A–Z of R.E.M. at the end of the feature.

There are no bonus features on the DVD; however, there is an optional lyrics subtitle track. Audio on the DVD-5 is PCM Stereo. The DVD was certified "15" in the UK due to nudity in 'Nightswimming'.

There were two versions released in the US. The "A Version" cut out the nudity from "Nightswimming," while the "D Version" contained the uncut video. A Parental Advisory warning was placed on the cover of the "D Version."

Parallel-M LTD is one of the leading operators in Ukraine's oil wholesale and retail markets. The company has been operating at the Ukrainian market of petroleum products since 1995.
