Sometimes yes. Sometimes no! There are certainly situations where a pixel will be scaled, displayed, edited or otherwise treated as a little square.

A little rectangle even.
What is a little rectangle? Physical display pixels are separate RGB leds with a non-rectangular shape.
Many video formats use rectangular pixels. It's less common these days, but there were no squares on DVDs for example.
Even some VGA modes have non-square pixels, and these were used by many games and... Windows 9x splash screen.
BBC Micro in graphics mode 2 the pixel is a 2:1 rectangle. Other geometries for different modes. It's going back a bit, but very much living memory!

In medical imaging, data are often acquired using anisotropic resolution. So a pixel (or voxel in 3D) can be an averaged signal sample originating from 2mm of tissue in one direction and 0.9mm in another direction.
