Eto'o – a three-time Champions League winner among other honours – last played for Qatari outfit Qatar SC in 2018-19.
And the 38-year-old ex-Cameroon striker appears set for life after football following Friday's Instagram post.
"THE END, TOWARDS A NEW CHALLENGE," Eto'o wrote. "Thank you all big love... adrenaline."
Eto'o enjoyed a trophy-laden career after emerging from Real Madrid's youth team in 1997 – making three appearances for the Spanish giants.
He won the Champions League twice with Barcelona and again during his time at Inter, where Eto'o was part of the club's 2009-10 treble-winning side.
In total, Eto'o celebrated 15 club titles – including three LaLiga trophies – following spells with Mallorca, Barca, Inter, Anzhi Makhachkala, Chelsea, Everton, Sampdoria, Antalyaspor, Konyaspor and Qatar SC.
Eto'o earned 118 caps for Cameroon as he became the country's all-time leading scorer with 56 goals, while winning two African Cup of Nations titles and gold at the 2000 Olympic Games.
