CTV Atlantic (formerly known as ATV) is a system of four television stations in the Canadian Maritimes, owned and operated by the CTV Television Network, a division of CTVglobemedia.

The CTV Atlantic stations are:

• CKCW - Moncton, New Brunswick and Charlottetown, Prince Edward Island
• CKLT - Saint John, New Brunswick and Fredericton, New Brunswick
• CJCH - Halifax, Nova Scotia
• CJCB - Sydney, Nova Scotia

All four stations refer to themselves on air as CTV, not by their call letters, and have common local programming for the most part, but are otherwise considered separate stations by the Canadian Radio-television and Telecommunications Commission (CRTC). Station information and history is discussed in each station's own article.
