Pochettino, a 48-year-old Argentine, was the only name in the frame to take over at the club where he played from 2001 to 2003 after PSG abruptly ended Tuchel's involvement on 24 December, reportedly for comments viewed as critical of the club's Qatari owners.
"This club has always held a special place in my heart. I have wonderful memories, especially of the unique atmosphere of the Parc des Princes," Pochettino said.
"I return to the club today with a lot of ambition and humility, and am eager to work with some of the world's most talented players."

Pochettino added he would do his utmost "to give our team the combative and attacking playing identity that Parisian fans have always loved".
His priority will be to sate the Qatari-backed club's quest for UEFA Champions League glory.
Tuchel, who oversaw the club's first ever UEFA Champions League final appearance last season, guided Neymar and company into the knock-out stages this season before being axed.
Pochettino's first major test will be the UEFA Champions League Round of16 away leg at Barcelona next month.
Pochettino will take charge of his first match next Sunday (AEDT) at Saint-Etienne as Ligue 1 resumes after the winter break with PSG one point off the leader in third.
Then, on 17 February (AEDT), he will be plotting the downfall of his compatriot Lionel Messi's Barcelona at the Camp Nou, with the return leg on 7 March (AEDT).
Like Tuchel, Pochettino was sacked after leading Spurs to their first ever appearance in a UEFA Champions League final, against Liverpool in 2019.
Although he has yet to win any silverware the former PSG defender's stock is high in managerial circles.
Pochettino made Tottenham a consistent UEFA Champions League qualifier in four years at the Premier League club before his departure in 2019.
He arrives in the French capital after being linked with a number of high-profile clubs, including Manchester United, Real Madrid and Barca.
He is due to meet up with the world's most expensive player Neymar, France's FIFA World Cup-winning forward Kylian Mbappe and their team-mates at PSG's first post-Christmas training session on Monday (AEDT).
His first coaching position was at struggling Espanyol, where in 2009 his first match in charge was against Barcelona.
He earned plaudits for saving the Spanish outfit, where he played under fellow Argentine Marcelo Bielsa in 1998, from relegation.
The son of a farmer from Murphy, in the north of Argentina, he will have under his wing several compatriots to count on such as Mauro Icardi, Angel Di Maria and Leandro Paredes.
Pochettino will be keen to take advantage of the transfer window to bring in new faces, with French newspaper Le Parisien identifying his former Spurs charge, Inter Milan's attacking midfielder Christian Eriksen, as one target.
Dele Alli, who has fallen out of favour under Jose Mourinho at Tottenham, is another.
Looking further ahead, given his Argentinean ties, Pochettino may be the catalyst for six-time Ballon d'Or winner Messi to consider PSG as a potential new employer when he is free to leave Barcelona at the end of the season.
