SampleTekk is a Swedish sample library developer founded in January 2004 and based in Stockholm. The company is run by Per Larsson and Niklas Flyckt, working largely out of Sveriges Radio's Studio 9. Beyond their own-brand releases, SampleTekk has produced sample content for other audio companies including Steinberg, Toontrack, Nord Keyboard, XLN Audio, Propellerhead, and Kurzweil.

The company is best known for multisampled acoustic and electric keyboard instruments, with a catalog centered on sampled grand pianos. Flagship titles include the 7CG MkII (a Yamaha C7 grand), White Grand MkII, Black Grand, Vertikal MkII upright, S.S.G. Small Studio Grand, Rain Piano MkII — inspired by the sound of Tom Waits' Mule Variations — and Singularis, which emulates late-1950s and early-1960s recording-era pianos. Libraries are offered for Native Instruments Kontakt, Steinberg HALion, and as standalone VST3/AU plugins.

Alongside pianos, SampleTekk has released sampled electric keyboards such as Clavinet and Pianet instruments, organs, a Solina string synth, Renaissance flutes, and marimba. Their libraries are generally recorded with multiple velocity layers and features such as sympathetic string resonance and pedal-noise modeling aimed at realistic acoustic performance.

Sampletekk has 2 products cataloged on Equipboard, including Kontakt Instrument.
