Richard Herring's Leicester Square Theatre Podcast (or RHLSTP (UK: )) and Richard Herring's Edinburgh Fringe Podcast are two related comedy podcasts, created and hosted by British comedian Richard Herring. Hosted on The British Comedy Guide, the podcasts are interviews with notable guests, usually fellow comedians. The original Edinburgh Fringe podcast ran from 2011 to 2013, and took place most days for the duration of the Fringe, focusing on interviews with performers at the festival. They also contain short stand-up segments from Fringe performers. The Leicester Square Theatre Podcast, recorded at Leicester Square in London, began in 2012 and follows a similar format, with higher profile guests. It runs for a shorter series than the Edinburgh Fringe version, with weekly recordings.

Both podcasts are performed in front of a paying audience, but released for free download and streaming. Series One and Two of the Leicester Square Theatre Podcast were released solely in audio format, with the exception of Stewart Lee's episode, which was initially released as a DVD Extra for Fist of Fun, Series Two. From Series Three onwards all episodes of the show were released in both audio and video format – initially as a paid download, then free on YouTube. Series Seven was the first to be financed by a Kickstarter campaign in order to cover the costs of production. Since Series Seventeen, Richard Herring's Leicester Square Theatre Podcast has been recorded on tour at different venues and, as such, has been referred to only by the acronym title of RHLSTP. After only one episode of Series Nineteen was recorded, the remainder of the series was postponed due to the COVID-19 pandemic. Herring has continued to conduct interviews and provide new content via Twitch during the lockdown. In March 2022 he started releasing the RHLSTP Book Club podcast on Fridays, recorded remotely, where he chatted with authors about one of their books.
