Pinoy Big Brother: All In is the fifth main season of the Philippine ABS-CBN reality television series Pinoy Big Brother and the eleventh season overall.

This was also the first season of the Big Brother franchise from the world to feature adult civilians, teenagers and celebrities taking part in the same season.

Due to the mixed contestant types this season is referred to as a "Special Edition".

Toni Gonzaga, Bianca Gonzalez, Robi Domingo, and John Prats reprised their roles as hosts, while Alex Gonzaga joins the show initially as a host but served as one of the longest-reigning houseguests.

The network officially announced the auditions on September 15, 2013, during an episode in The Voice of the Philippines.

The official air date was not revealed in the announcement.

On November 6, 2013, Toni Gonzaga was officially confirmed to return as the main host of the show.

Also, according to Lauren Dyogi, both Bianca Gonzalez and Robi Domingo were expected to return to co-host the show.

Initially the auditions for the fifth season were to be held on October 6, 2013, at the Quezon Memorial Circle in Quezon City as part of the network's 60th anniversary celebration.

However, the said auditions venue was postponed due to security and logistical issues.

On November 30, 2013, it was announced that, for the first time in the franchise, there would be online auditions through one-minute video submissions.

Online auditions ran from December 1, 2013, until January 15, 2014.

On March 27, Dyogi announced that 33,064 people auditioned, of which 11,265 were online auditions.

A grand mini reunion, attended by some of the former housemates of the Regular, Celebrity and Teen Seasons and hosts of the show, was also held at ASAP 19 on April 20.

In an interview aired February 10, 2014, on Banana Nite, Toni Gonzaga confirmed that the show will return in March 2014.

It was later moved on April 27, 2014.

Every Thursday night in the online Twitter discussion, Business Unit head of the franchise Lauren Dyogi, the hosts, and former housemates will answer the questions of the netizens.

On April 27, 2014, the show introduced two housemates in ASAP 19 and three housemates in Buzz ng Bayan, which were both ahead of Pinoy Big Brother's timeslot.

The rest of the housemates were introduced in the show itself later that night.

In late March 2014, John Prats was confirmed to return and reprise his previous hosting duties.

On the other hand, Domingo will be the segment host of Pinoy Big Brother Update, which will air every afternoons and evenings, and will be joining Prats, and Gonzalez on Pinoy Big Brother: All In Über.
