Short answer -- yes. Long answer -- Champions League is an annual tournament through UEFA (Union Européenne de Football Association/"European Union of Association Football"). Different countries/leagues have different numbers of qualifying teams, and Wikipedia has a breakdown of how many by country/league. I'll use this Premier League season as an example - the top four teams in the standings at the end of the '12-'13 season will qualify for the '13-'14 CL. If the season ended today, those four teams would be Man. Utd., Man. City, Chelsea, & Spurs. Here is the "Competition Format" page from the UEFA website, which explains how the CL group play & knockout stage work. Quick version: Qualifying round → Group/Round-robin stage → Knockout stage. Reading the Wikipedia page on CL qualification might also help. There's also one loophole for qualification -- winning the previous season's CL. Chelsea actually went this route for this season's CL -- they won the CL last season, so even though they finished 6th in the '11-'12 Premier League, they automatically qualified for the '12-'13 CL. However, that came at the expense of Tottenham Hotspur (Spurs), who finished 4th & would normally have qualified for the CL*. Incidentally, this season Chelsea also became the first-ever defending CL champ to not get out of the group stage in the following CL competition. * Spurs instead qualified for the '12-'13 UEFA Europa League. To explain this would be another long-ish post, but it's fairly similar to the CL. However, for a familiar comparison, think NCAA Men's Hoops tourney (CL) v. the NIT tourney (Europa Lg.) EDIT: Here is the Wikipedia page on the Europa League in general, if you're interested in reading up on it as well.
