Mega Man Battle Network 5, known as Rockman EXE5 (ロックマンエグゼ５ Rokkuman Eguze Faibu) or Rockman EXE 5 in Japan, is the fifth mainline game in the Mega Man Battle Network series released for the Nintendo Game Boy Advance. It follows Lan Hikari and MegaMan as they continue their fight against Nebula, who has begun their campaign to conquer the cyberworld.

Mega Man Battle Network 5 came in two versions: Team ProtoMan and Team Colonel, known as Team of Blues (チーム オブ ブルース Chīmu Obu Burūsu) and Team of Colonel (チーム オブ カーネル Chīmu Obu Kāneru) in Japan, known as Team Blues and Team Colonel in the Chinese version of Mega Man Battle Network Legacy Collection. Like Mega Man Battle Network 3, in Japan, Team ProtoMan was released by itself first with Team Colonel coming out months later. Despite that, Team Colonel contains the same bugs Team ProtoMan had.

A few months later, an advanced port called Mega Man Battle Network 5: Double Team DS, was released for the Nintendo DS which included content from both GBA versions together with extras and bugfixes.

Story elements from Battle Network 5 were loosely adapted for the Rockman EXE Stream anime and for the film Rockman EXE: Hikari to Yami no Program. A sixth and the final game in the Mega Man Battle Network series, Mega Man Battle Network 6, was released the following year.
